9. Is your domain alright?

Last updated 1 year ago

Here's how you can troubleshoot deliverability.

It is highly recommended you pinpoint the issue yourself before requesting help in your Slack channel to save time.

  1. Pick the domain that has issues.

  2. Open the .csv given to you for the domain:

  1. Open any mail application (Like macOS' Mail app or even Outlook for Windows/macOS) and log in with a randomly picked address from the .csv:

  1. Paste the code in the email and then write a realistic office email, nothing too fancy but nothing too sloppy, imagine you're writing to your employees about something.

  2. Click on the addresses in Mailreach and click on "Line break", then copy the addresses.

  3. Paste the addresses on the "To:" field:

  1. Write a decent subject line:

  1. Make sure the code is pasted in the body of the email and then press send:

  1. Wait for Mailreach's results:

If you scored 10/10:

Your assigned server and domain are healthy. If you face any open rate issues, make sure your emails are interesting, non-spammy and being sent to a live, high quality list.

If your Mailreach test shows you're going to spam:

You did something wrong along the process. Sending spammy links like bit.ly, using poor and generic spintaxing and/or personalization and sending to unverified lists that generate bounces are all causes of going to spam.

Talk in your assigned Slack channel to replace your domain if you want to, or let the warmup run for a week without doing outreach to heal it.

If your Mailreach test shows your email is missing:

This is grave. This means your server was damaged from low-quality, aggressive sending. You'll know if the Mailreach test shows missing emails after ten minutes, and if your inbox has something like this:

If this is the case, you must talk in your assigned Slack channel to get a new server so you can continue emailing.

Go to and then copy the code you see:
