How To Prevent Emails From Going to Spam

STEP 1: Set up Email Authentication

Proper email authentication tells Gmail and other mailbox providers that who’s sending the email is not a bad actor.

If a mailbox provider is confident you’re a legitimate entity, there’s a higher chance your email will drop in users’ inboxes.

There are three popular ways to authenticate your email. These are:

  1. SPF
  2. DKIM
  3. DMARC


Sender Policy Framework or SPF compares your IP to the IP addresses authorized to send emails from your domain.

See this as a list of IP addresses you’ve whitelisted to send emails from your domain name.

For example, this is the SPF TXT record that Google Workspace uses to authenticate emails:

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

This is for Mailchimp:

v=spf1 include:servers.mcsv.net ?all

To enter this text in your domain name server (DNS), you’ll have to log into your domain host console and locate where to update the DNS TXT information for your domain.


DKIM stands for DomainKeys Identified Mail.

Think of it like an invisible signature, secured with encryption, added to the emails you send.

Mailbox providers can authenticate this signature to ensure the email is from a legitimate account. For example, all outgoing emails from Google servers are signed with:


You can also set up DKIM by adding the TXT signature you get from your email hosting service to your domain’s DNS.


DMARC (Domain Message Authentication Reporting and Conformance) is a protocol used to tell the receiving email servers how they should deal with emails that fail DKIM and SPF authentication.

STEP 2: Clean Your Email List

Where did you get your email list? Did users subscribe to your newsletter, or you bought a list from somewhere?

The latter option poses lots of risks and could account for your emails going to spam.

They’re more than likely to move your email to spam if it makes it to their inbox, assuming the email wasn’t flagged as spam initially.

Consequently, inbox providers would see your domain and the emails you send as inconveniencing to their users and move them to spam.

They may altogether ignore your email. This results in low engagement and is equally bad for you.

Bought email lists also typically contain email addresses that are no longer active.

Having more inactive email addresses in your list than active ones is a tell-tale sign to mailbox providers that you’re likely sending spam.

When mailbox providers notice this, they are more inclined to classify your emails as spam.

The best way to solve this problem is to painstakingly build your email list from those who surrender their email to you.

Also, ensure you’re not enticing the wrong subscribers because in the long run, engagement will drop.

Lastly, allow users to opt-out by providing an unsubscribe option in your emails.

STEP 3: Employ Email Content Best Practices

Below are some best practices you can adopt in your email subject line and body. These include:

  • Avoid misleading subject lines. Ensure the content and context of the body aligns with what’s in the subject line. Also, tone down on outlandish claims in the subject line.
  • Avoid spam trigger words in the body and subject line: There’s no exhaustive list of spam triggers anywhere, but you bet that writing “$$$$” or “!!!!!” or writing in ALL CAPS in your email is courting trouble with spam algorithms. They are similar to the triggers caught by WordPress anti-spam solutions.
  • Avoid spelling and grammatical mistakes. Spam emails are legendary for headache-inducing grammar and spelling mistakes.
  • Avoid sending attachments: While this is sometimes unavoidable, it’s always best not to include them (pictures, files, etc.). They are spam triggers because they pose a security threat in the form of malware and viruses.
  • Ensure the information in the “From” line is accurate and not just something random.
  • Include your company address in the email.

How often you send emails matters. You don’t want users to feel like you’re pestering them. Limit the emails to important information only.

STEP 4: Ask your Subscribers to Whitelist Your Email Address

There’s no better way to prevent your emails from going to spam than for users to whitelist your email address.

Whitelisting your email tells mailbox providers that users trust you.

When you send the welcome email to new subscribers, always politely ask them to whitelist your email address.
