Category: Email Deliverability

If your cold emails are landing in spam, the problem almost certainly isn’t your copy — it’s your infrastructure. Email authentication records (MX, SPF, DKIM, and DMARC) are the DNS-level signals that tell receiving mail servers your domain is legitimate and your sending is authorized. Without them, even the best-written cold email gets filtered before anyone reads it. At COLDICP, proper email infrastructure setup is the foundation of every outbound system we build — it’s how we consistently achieve 98%+ inbox placement rates for clients. This guide walks through every record you need, how to set it up, and what to check before your first send.

Why Email Authentication Matters for Cold Outreach

Cold outreach operates in a high-scrutiny environment. You’re sending unsolicited email from a domain the recipient has never interacted with. Mail servers at Google, Microsoft, and other providers run authentication checks on every inbound message. If your domain fails those checks, your email either goes to spam or gets rejected entirely.

The four authentication layers — MX, SPF, DKIM, and DMARC — work together to prove three things:

• MX: Your domain can receive email (proving it’s a real, active domain)
• SPF: The server sending your email is authorized to send on behalf of your domain
• DKIM: Your email hasn’t been tampered with in transit (cryptographic signature)
• DMARC: What to do if SPF or DKIM fails — and who to notify

Skipping any of these is like cold calling from an unknown number with no caller ID. Carriers and recipients don’t trust it. See our guide on inbound vs outbound for more context on why infrastructure investment pays off in outbound-led growth.

What Is an MX Record and How to Set It Up

An MX (Mail Exchange) record tells the internet where to deliver email sent to your domain. Without an MX record, your domain looks like it can’t receive email — which is a major spam signal for outbound senders.

How to set it up:

1. Log in to your domain registrar or DNS provider (GoDaddy, Cloudflare, Namecheap, etc.)
2. Navigate to DNS settings for your sending domain
3. Add MX records pointing to your email provider’s mail servers

Example (Google Workspace):

Type	Name	Value	Priority
MX	@	aspmx.l.google.com	1
MX	@	alt1.aspmx.l.google.com	5
MX	@	alt2.aspmx.l.google.com	10

Your email provider will give you their specific MX values. Use the exact values they provide.

How to Set Up SPF

SPF (Sender Policy Framework) is a DNS TXT record that lists which mail servers are authorized to send email from your domain. When a receiving server gets an email from you, it checks your SPF record to confirm the sending server is on the approved list.

How to set it up:

1. Go to your DNS settings
2. Create a new TXT record at the root of your domain (@)
3. Add your SPF record as the value

Example SPF record (Google Workspace + Instantly):

v=spf1 include:_spf.google.com include:spf.instantlyai.com ~all

Key rules:

• You can only have one SPF TXT record per domain. Combine all senders into a single record.
• Use ~all (softfail) rather than -all (hardfail) during initial setup to avoid blocking legitimate mail while you test.
• Keep your include count under 10 DNS lookups to avoid SPF PermError.

How to Set Up DKIM

DKIM (DomainKeys Identified Mail) adds a cryptographic signature to your outgoing emails. The receiving server uses a public key stored in your DNS to verify that the email was actually sent by you and hasn’t been altered in transit.

How to set it up:

1. Log in to your email sending platform (Google Workspace, Instantly, Smartlead, etc.)
2. Navigate to the DKIM settings — your platform will generate a public/private key pair
3. Copy the CNAME or TXT record the platform provides
4. Add it to your DNS as a TXT record, typically at a subdomain like google._domainkey.yourdomain.com
5. Return to your email platform and click Verify / Authenticate

Example DKIM DNS entry:

Type	Name	Value
TXT	google._domainkey	v=DKIM1; k=rsa; p=MIGfMA0GCS…

Each sending platform generates its own DKIM key. If you send from multiple platforms, set up a separate DKIM record for each.

How to Set Up DMARC

DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving mail servers what to do when an email fails SPF or DKIM checks. It also sends you aggregate reports on authentication failures — which is useful for monitoring deliverability.

How to set it up:

1. Add a TXT record to your DNS at _dmarc.yourdomain.com
2. Start with a monitoring-only policy, then tighten it over time

Example DMARC record (start here):

v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com

DMARC policy options:

• p=none: Monitor only — no action taken on failures. Start here.
• p=quarantine: Failed emails go to spam. Use after confirming SPF/DKIM are working.
• p=reject: Failed emails are blocked entirely. Use only when you’re fully confident in your setup.

Setting Up Email Forwarding

For cold outreach, many teams use secondary domains (e.g., usecoldicp.com alongside coldicp.com) to protect their primary domain’s reputation. Setting up email forwarding from your sending domains to your main inbox ensures replies don’t get lost.

Most email providers (Google Workspace, Microsoft 365) offer forwarding rules in their admin settings. Alternatively, route forwarding through your CRM or inbox management tool to keep reply tracking intact.

Domain Warmup Protocol After Setup

Authentication records prove your domain is legitimate — but a brand new domain with zero sending history still looks suspicious to mail servers. Domain warmup gradually builds your sender reputation by starting with low send volumes and increasing over 4–6 weeks.

Standard warmup schedule:

• Week 1–2: 10–20 emails/day. Send only to engaged contacts or warm leads.
• Week 3–4: 50–100 emails/day. Monitor open rates and spam complaints closely.
• Week 5–6: 200–300 emails/day. If metrics are clean, you’re ready to scale.
• Full scale: 200–500 emails/domain/day maximum for cold outreach.

Use a dedicated warmup tool (Instantly’s warmup, Smartlead warmup, or Mailreach) alongside manual warmup sends for the first two weeks. Once your cold email copy is ready, a warmed domain means your first send actually lands.

5 Common Mistakes That Kill Deliverability

• One domain for everything: Never use your primary business domain for cold outreach. Set up 3–5 sending domains minimum and rotate volume across them.
• Missing DMARC: Even a p=none DMARC record is required by Google and Yahoo for bulk senders since February 2024. Not having one gets your emails flagged.
• Overloading SPF includes: Each include= in your SPF record triggers a DNS lookup. Exceeding 10 lookups causes SPF PermError — your emails fail authentication even if your record looks correct.
• Sending cold to unverified lists: High bounce rates (above 2%) tank sender reputation fast. Verify every email address before sending.
• Skipping warmup on new domains: Going from zero to 500 emails/day on a new domain is the fastest way to get blacklisted. Warmup is not optional.

How to Verify Your Setup

Before sending a single cold email, verify every record is configured correctly:

• MXToolbox: Check MX, SPF, DKIM, and DMARC records. Run the Email Health report for a full audit.
• Mail-tester.com: Send a test email and get a deliverability score out of 10. Aim for 9+.
• Google Postmaster Tools: Monitor your domain reputation and spam rate with Google’s mail servers directly.
• GlockApps: Test inbox placement across multiple providers (Gmail, Outlook, Yahoo) simultaneously.

Conclusion

Email infrastructure is the unsexy foundation that determines whether everything else works. Get your MX, SPF, DKIM, and DMARC records right before you write a single cold email — and warm your domain properly before you hit scale. If you want COLDICP to build and maintain the infrastructure for you (including multi-domain architecture, continuous monitoring, and 98%+ inbox rates), apply for the GTM Pilot.

Frequently Asked Questions

Do I need separate domains for cold email?

Yes. Always use secondary sending domains for cold outreach — never your primary business domain. If a sending domain gets blacklisted, your main domain (and its reputation for transactional and marketing email) stays clean. Set up a minimum of 3–5 sending domains with slight variations of your brand name.

How long does it take for DNS records to propagate?

Most DNS changes propagate within 15–60 minutes, but full global propagation can take up to 48 hours. Use MXToolbox to check record visibility after changes. Don’t start sending until all records are confirmed active.

What’s the difference between SPF softfail (~all) and hardfail (-all)?

Softfail (~all) marks emails from unauthorized servers as suspicious but still delivers them. Hardfail (-all) rejects them outright. Start with softfail while you verify your setup, then move to hardfail once you’re confident all your legitimate sending sources are included in your SPF record.

Over 22% of all email campaigns see their messages never reaching the intended recipients. Understanding the difference between a hard bounce vs soft bounce can be crucial in optimizing your email deliverability. These terms might sound technical, but they have real implications on how your outreach efforts are received.

Hard bounces are permanent delivery failures usually caused by invalid email addresses or non-existent domains. On the other hand, soft bounces are temporary setbacks often due to a full inbox or server issues. Both types of bounces impact your sender reputation, but addressing the root causes of hard bounces is vital as they signal a persistent problem in your email strategy.

Feature	Hard Bounce	Soft Bounce
Type of Issue	Permanent	Temporary
Impact on Sender Reputation	High	Low
Required Action	Immediate removal or correction	Monitor and retry later
Common Causes	Invalid email address, non-existent domain	Full inbox, server issues
Automatic Resolution	No	Yes, sometimes

Overview of Hard Bounce and Soft Bounce

Emails don’t always reach their destination. Sometimes, they bounce back. These bounces come in two types: hard bounce and soft bounce.

Overview of Hard Bounce

A hard bounce happens when an email can’t be delivered at all. This could be because the email address is wrong. It could also be that the domain doesn’t exist.

Hard bounces are permanent issues. They don’t fix themselves over time. You have to remove these addresses from your list.

These bounces hurt your email sender reputation. Too many hard bounces can get you marked as a spammer. This makes it harder for your emails to get through in the future.

Companies should keep their email lists clean. This means checking and updating email addresses. Removing invalid ones helps a lot.

It’s important to monitor bounce rates. High hard bounce rates can show bigger problems. Addressing these can improve your email success.

Overview of Soft Bounce

Soft bounces are different from hard bounces. They happen when there’s a temporary problem. This could be because the recipient’s mailbox is full.

Sometimes, a server issue causes a soft bounce. This means the email is not delivered right now. But it might be delivered later.

Soft bounces don’t hurt your sender reputation as much. They’re seen as less serious. But you still need to watch them.

If an address keeps soft bouncing, it might become a hard bounce. Check these addresses often. Make updates as needed.

Soft bounces can tell you useful things. They can highlight temporary issues. Fixing these can help your emails get through next time.

Key Features Compared: Hard Bounce Vs Soft Bounce

Hard bounces and soft bounces have different features. Understanding these can help improve your email strategy. Let’s compare them.

Failure Type

Hard bounces indicate a permanent delivery failure. The email address might be wrong. Or maybe it doesn’t exist anymore.

Soft bounces show a temporary issue. This can mean the mailbox is full. Sometimes, it’s because of a temporary server issue.

For hard bounces, the problem won’t fix itself. You have to take action. Usually, this means removing the email address.

Soft bounces, however, might resolve on their own. The email could be delivered later. Keep an eye on these addresses.

Understanding the failure type helps you decide what to do next. Whether to remove the address or try again later. This can save you time and effort.

Impact on Sender Reputation

Hard bounces can really hurt your sender reputation. If too many emails bounce, your emails may get blocked. People might see you as a spammer.

Soft bounces don’t have as big of an impact. They are seen as temporary problems. But still, they should be monitored.

Maintaining a clean list helps your sender reputation. Remove hard bounces quickly. This keeps your reputation strong.

Soft bounces require less immediate action. You can try sending the email again later. Monitor these over time to ensure they don’t turn into hard bounces.

Reputation matters for email deliverability. Keeping both types of bounces low helps. This ensures your emails reach more people.

Causes of Bounce

Hard bounces often come from invalid email addresses. These can be typos or old, inactive accounts. Another cause is non-existent domains.

Soft bounces have different causes. A full inbox is a common one. Sometimes, the recipient’s email server might be down.

Knowing the causes helps you troubleshoot. For hard bounces, correct the email address. Or remove it from your list.

For soft bounces, try resending the email later. Notify the recipient if possible. They might need to clear their inbox.

Different causes need different solutions. Identifying the cause quickly is key. This can improve your email campaign’s success.

Required Action

Hard bounces require immediate action. You need to remove or fix the email address. Leaving it on your list can cause more problems.

Soft bounces need monitoring. See if they resolve on their own. If not, consider following up with the recipient.

Ignoring hard bounces is risky. Your sender reputation can suffer. Always act quickly to address them.

Soft bounces are less urgent but still important. Keep track of these bounces. They might become hard bounces later.

Knowing what action to take helps manage your email list. This keeps your campaigns more effective. It also protects your reputation.

Long-Term Effects

Hard bounces have long-term effects on your email campaign. They can diminish your sender reputation. This makes future emails harder to deliver.

Soft bounces have less severe long-term effects. But if ignored, they can turn into hard bounces. This can then affect your reputation.

Reducing hard bounces helps maintain list health. Clean lists perform better. They also have higher engagement rates.

Soft bounces offer a chance to improve. They highlight temporary issues. Fix these to enhance future deliverability.

Understanding the long-term effects helps in planning. Managing both types of bounces is crucial. This ensures ongoing email success.

SMTP Vs IMAP, Two of the most significant protocols in this realm are Simple Mail Transfer Protocol (SMTP) and Internet Message Access Protocol (IMAP).

SMTP, developed in the early 1980s, is responsible for sending and forwarding emails between servers. In contrast, IMAP, introduced a bit later, allows users to access and manage their emails directly on a mail server. While SMTP pushes messages out, IMAP provides a seamless way to retrieve and organize them efficiently.

Feature	SMTP	IMAP
Email Direction	Sending emails	Receiving and managing emails
Synchronization	Does not sync	Syncs across multiple devices
Storage Location	Does not store	Stores emails on server
Access	Focused on sending	Accessible from any device
Organization	No email organization features	Allows organization with folders

Overview of SMTP and IMAP

SMTP and IMAP are vital protocols used for handling emails. While they might sound complex, their functions are essential for email communication. Let’s explore what each one does.

Overview of SMTP

SMTP stands for Simple Mail Transfer Protocol. It’s the system that sends emails from one server to another. Think of it as the postal service for email.

SMTP was created in the early 1980s. It handles outgoing mail, ensuring your email reaches the intended recipient. Without SMTP, sending emails would be impossible.

SMTP focuses on delivering emails quickly and reliably. When you hit ‘send,’ SMTP takes over to do its job. It works behind the scenes to transfer your message.

Servers communicate using SMTP to relay messages. This ensures that an email from one person reaches another person’s inbox. The process is seamless and fast.

SMTP is crucial for sending and forwarding emails. It’s the backbone of email transmission. With it, your email can travel around the world in seconds.

Overview of IMAP

IMAP stands for Internet Message Access Protocol. This protocol allows you to access and manage your emails on a server. It’s like having a remote control for your emails.

IMAP was introduced after SMTP, offering advanced email management. It lets you read, delete, or organize your emails online. This means you don’t need to download them to your computer.

IMAP synchronizes your email across multiple devices. Check your mail on your phone, and you’ll see the same emails on your computer. It ensures consistency and convenience.

With IMAP, emails remain on the mail server. This keeps your inbox up-to-date no matter where you log in from. Changes on one device update across all others.

IMAP is excellent for those who use multiple devices for email. It provides flexibility and control. You can manage your emails from anywhere, anytime.

Key Features of SMTP and IMAP

SMTP and IMAP are essential for handling emails. Each has unique features that make email communication efficient. Let’s compare their key features.

Email Transmission

SMTP is designed for sending emails. When you hit ‘send,’ SMTP ensures your email gets to the right place. It acts like a mailman, delivering messages.

IMAP, on the other hand, focuses on receiving and organizing emails. It lets you see your emails from any device. IMAP doesn’t focus on sending; it’s all about accessing.

With SMTP, outgoing emails travel from your server to another. This is crucial for delivering your messages. Without SMTP, your emails wouldn’t reach their destination.

IMAP receives emails, storing them on a server. It makes sure you can access your messages from anywhere. While SMTP sends, IMAP retrieves and organizes emails.

Both protocols are vital. SMTP handles sending, while IMAP focuses on receiving. Together, they make email communication smooth and efficient.

Synchronization

IMAP specializes in synchronizing emails across devices. Read an email on your phone, and it appears as read on your computer too. This keeps everything in sync.

SMTP doesn’t handle synchronization. It’s only for sending emails. Once an email is sent, SMTP’s job is done.

IMAP ensures that any action you take on one device reflects on others. Delete an email on your laptop, and it’s gone on your tablet too. This feature is great for managing emails seamlessly.

With IMAP, all devices display the same email status. This is particularly useful for busy individuals. Synchronization keeps your email consistent across platforms.

While SMTP is crucial for sending, IMAP’s synchronization provides added convenience. Together, they cover both aspects of email handling. No email gets lost in the shuffle.

Storage

IMAP stores emails on the server. This means you can access them from multiple devices. It’s like cloud storage but for emails.

SMTP doesn’t store emails. After sending, it’s the recipient’s server job to store the email. SMTP’s role is limited to delivering.

With IMAP, your mailbox is always up-to-date. Emails remain on the server until you delete them. This provides flexibility.

IMAP’s storage on the server means you don’t need to download emails. You can read them directly from the server. Storage with IMAP is both convenient and efficient.

SMTP relies on the destination server for storage. IMAP keeps everything accessible on the server. Each has a distinct role in email management.

Accessibility

IMAP excels at making emails accessible from different devices. Whether you use a phone, tablet, or PC, IMAP has you covered. It adapts to your needs.

SMTP doesn’t offer accessibility features. Its main task is to send emails out. Once sent, its job is complete.

IMAP allows you to manage your inbox from anywhere. This is perfect for people who use multiple devices. You’re always connected to your emails.

With IMAP, accessibility is seamless. Any changes you make on one device appear on others. This makes managing emails simple and straightforward.

In terms of accessibility, IMAP is a clear winner. It ensures you can access your emails from any device. SMTP doesn’t offer these features but is essential for sending.

Email Organization

IMAP helps you organize your emails. You can create folders and manage messages. This keeps your inbox neat and tidy.

SMTP doesn’t focus on organization. Its job is to send emails only. It leaves organizing to the recipient’s server.

With IMAP, you can move emails into folders. This makes finding important emails easier. Organizing with IMAP is user-friendly.

IMAP allows you to mark emails as read or unread. You can also flag important messages. This feature helps in managing emails efficiently.

Email organization is a key strength of IMAP. It provides tools to keep your inbox orderly. SMTP, on the other hand, is solely for sending emails.

Frequently Asked Questions

SMTP and IMAP are crucial email protocols. While they both play important roles, they serve different purposes. Here are some common questions to help understand their differences and functions.

What is the primary function of SMTP?

SMTP, or Simple Mail Transfer Protocol, is primarily used for sending emails. It acts as a mailman, delivering your messages to the recipient’s mail server.

When you hit ‘send,’ SMTP takes over, ensuring your email travels from your server to the recipient’s server. This process happens behind the scenes and is essential for email transmission.

How does IMAP work for email access?

IMAP, or Internet Message Access Protocol, allows you to access and manage your emails directly on a server. This means you can read, delete, and organize your messages online without downloading them.

IMAP syncs your email across multiple devices. When you check your email on your phone, computer, or tablet, IMAP ensures you see the same messages and changes on all devices.

Can SMTP be used for receiving emails?

No, SMTP is designed specifically for sending emails. It pushes messages out to the recipient’s server but does not handle incoming emails.

For receiving and managing incoming emails, protocols like IMAP or POP3 (Post Office Protocol) are used. SMTP complements these protocols, handling only the sending part of email communication.

Why would someone choose IMAP over POP3?

IMAP has more advanced features compared to POP3. While POP3 downloads emails to your device and often deletes them from the server, IMAP allows you to keep emails on the server and access them from multiple devices.

This makes IMAP ideal for people who need to access their emails on different devices and maintain synchronization. It keeps your email management consistent no matter where you log in from.

Are there additional costs involved in using SMTP or IMAP?

Generally, both SMTP and IMAP are included in most email hosting services. However, there may be additional costs for premium features like increased storage or higher sending limits.

Some services might charge extra for bulk email sending with SMTP, while IMAP might incur costs if you need more storage space on the server. It’s essential to review your service provider’s pricing structure.

Final Thoughts

SMTP and IMAP are both indispensable in the realm of email communication. While SMTP focuses on sending emails efficiently, IMAP allows you to manage and organize your emails seamlessly across multiple devices.
