A cut above the rest of the mailmerge options available. Super easy to use and a generous free plan. Plus, importantly, it doesn't request permission to read my emails.




This add on is extremely practical and easy to use. Saves me a lot of time when emailing multiple recipients. I highly recommend it!





Helps in sending mails to multiple recipients and helps personalizing the content. Good app.





One of the best email marketing tool to send personalize emails to maximum number of contacts in a given time.





Makes your recipients feel unique when compared to an email blast from a Mailchimp style platform. I love it, especially for smaller lists where you need a personal touch.





Of all the mail merge add-ons I've used for Google Sheets, this one is so far my favorite. I especially love how the templates don't have to be stored in my Gmail drafts. Super easy, great interface, pretty smooth add-on.

You can send up to 100 emails a day with Mailmeteor for free. We've doubled the free quota compared to existing mail merge solutions. If you want to benefit from premium features and unlock your sending limit, you can upgrade your account on our paid plans.
Mailmeteor lets you send email campaigns from your Gmail inbox, contrary to email marketing softwares - like Mailchimp or Sendgrid. For your recipients, it is as if you actually wrote each and every emails. It means better email deliverability, less spams and way better opening rates!

You can also compare Mailmeteor to other mail merge extensions for Gmail - like Yet another mail merge or Gmass. Mailmeteor is different in three ways:
  • Privacy first - Mailmeteor never requires access to your email data while other add-ons (like YAMM or Gmass) can read, modify and delete your emails.
  • Stellar user experience - Mailmeteor is built to make mail merge easier. Send your first campaign in a few simple steps.
  • Affordable pricing - starting from $2.5 a month per user. Simple pricing that works at any scale.
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 If your campaigns have a lot of bounced or undelivered emails, Google will detect that your database is outdated or not legitimate.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 between 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 (number of emails, date of sending, sheet's name - that's all)
  • Emails sent metadata (date of sending, opens and clicks events - that's all again)

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.
