Email deliverability is a complex topic but there are simple things you can do to make sure your emails don't get caught by spam filters.

  1. Set up domain authentication (DKIM, SPF) and custom tracking domain. This is technical and 100% unexciting but the good news is it's binary: once you do this you'll start seeing results right away. Read our detailed instructions for authenticating your domain and setting up custom domain tracking.

  2. Do not send emails to purchased lists. This is a serious no-no and can lead to account suspension. Sending emails to purchased lists is not allowed via Outfunnel.

  3. Maintain good data collection practices. Use double opt-in confirmation for contacts that sign up via form before sending emails to them. Without using double opt-in spam traps may sign up to your lists. Emailing spam trap accounts may lead to account suspension.

  4. Clean your lists if someone hasn't engaged for 6 months. Invalid and stagnant emails in your list lower your deliverability rate and might trigger email providers to mark your emails as spam.

    1. We recommend using tools like MyEmailVerifier to clean your lists every 6 months.

    2. We recommend removing contacts that haven't opened your emails in 6 months

  5. Avoid words that trigger spam filters and structure emails to look like normal emails. Spammers have "trained" inbox filters to recognize certain words as strong signals for spam. Sometimes you can recognize these words from a mile away (eg. viagra or weight loss plan) but some spam trigger words look perfectly legitimate (eg. email marketing or laser printer). Consult this article to know which words to avoid in your emails. Make sure to also avoid shortened URLs (like bit.ly for example) as they can trigger spam filters. Links in the email content should be visible and easy to understand so recipients know where they go when they click them. Also, we recommend keeping a text-to-image ration around 80:20 and no more than 1-3 links per email.

  6. If you're using a brand new domain, warm it up first. Start small and gradually increase the volume of emails you send (for example 50 emails per day on the first week, 100 emails per day on the second week, etc.). You'll also want to generate some incoming email traffic. For example, sign up for some high-quality newsletters (think NYTimes, or why not our email course) and ask people to reply to your emails.
