How to avoid spam and improve your email open rate

Mailmeteor directly sends emails from your Gmail account, it prevents your email from falling into spams. However, please be sure to abide by Google anti-spam policies:

  • Warm-up your Gmail account. If your account is new, we recommend sending emails to a small list of recipients at first (less than 50 emails).

  • Stagger mass communications over 2 days— for large campaigns, try sending messages to one group of recipients, wait 24 hours, and then send to another group.

  • Make sure your contact list is clean. If your campaigns have a lot of bounced or undelivered emails, Google will detect that your database is outdated or not legitimate. We strongly recommended you to keep your database as clean as possible. If we detect spamming behavior, we will have to block your account.

  • Insert unsubscribe links in your emails if you are running marketing campaigns.

Why my emails go to spam?

You may wonder, why your emails go to spam? First things first, spam are all unsolicited or undesired emails. To keep account safe and prevent spam, email providers have developed anti-spam filters. Knowing the best practices will help you avoid spam:

  • Your reputation: if your emails have been flagged as spams in the past, spam filters will recognize your IP as spam. We recommend you to keep your sending clean so as not to harm your account or domain's reputation.

  • Email content and formatting: spam filters can check email content to ensure it does not contain phishing or scam. Also, we recommend you to keep formatting as simple as possible, avoid uppercases, combination of fonts or colors, abusive use of exclamation marks.

  • Email headers (or metadata): these include the following fields: Date, From, To, and Subject of your email. Spam filters will check these fields to ensure there is nothing unusual there.

  • HTML code of your email: unstructured HTML code will be suspect to spam filters. Mailmeteor email editor is built on Gmail's native technology, that should clean your email format. However, we recommend you to create your email directly in the editor instead of copy pasting text from Word, Google Docs or using an HTML template.
