Contrary to email marketing softwares (like Mailchimp) Mailmeteor lets you send mail merge right from your Gmail inbox. As if you actually wrote each and every emails. It means better email deliverability, less spams and way better opening rates! You could also compare Mailmeteor to other mail merge extensions for Gmail (like Yet another mail merge or Gmass). Mailmeteor is different because it's built on the latest technologies released by Google. It makes Mailmeteor the fastest and most reliable mail merge add-on for Gmail.
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).
  • 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 If your campaigns have a lot of bounced or undelivered emails, Google will detect that your database is outdated or not legitimate.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.
The only limit is your imagination! You can personalize every part of the email, from subject to content. Some examples:
  • Personalized email subject. For example: "Partnership betwen and Mailmeteor?"
  • Personalized greetings and recipients name like "Ghostbusters, whatya want?"
  • Personalized content: you can add personal notes, custom URLs, postscriptum...
By design, your data stays at all times on your Google Spreadsheet. Here's all the data we need in order to make Mailmeteor work:
  • Your email address - to know who you are
  • If you are a paying customer, your name to identify payment
  • Campaigns sent metadata (date of sending, sheet's name - that's all)
  • Emails sent metadata (email ID in Gmail, date of sending, open and clicks events - that's all again)
Mailmeteor complies with the French Data Protection Laws and the European General Data Protection Regulation 2016/679 (GDPR). You have a right of access, correction and removal of your personal data which you may exercise by sending us a support ticket directly on the support chat or by sending an email at
Mailmeteor is able to add a tracking status column to your sheet after sending. You can access all the stats directly from there, or open the Mailmeteor sidebar for more detailed stats.
Sure you can. Add a column in your sheet with "cc" or "bcc" as header. Put emails in the cells, if you have several recipients in CC or BCC, separate emails with comma. Video tutorial available here.

A meteor is small rocky or metal object from space that enters the Earth’s atmosphere and vaporizes. It is shooting star. Mailmeteor project was born during the Geminids, a meteor shower near the Gemini constellation. Meteors are debris from comets or asteroids, bodies of ice, rock and dust that orbits the sun and can be miles of diameter. Learn more on NASA's blog about these fascinating objects.
