Type: Google add-on

Mailmeteor is one of the most popular and most established Gmail mail merge extensions on the Google Workspace Marketplace today. In just three years, it has been ranked as the best-rated Google add-on, now used by more than 2.5 million users.

The extension was founded by Jean Dubrulle and Corentin Brossault, two Google specialists and entrepreneurs from Paris, France. Prior to building Mailmeteor, they were using other mail merge add-ons but got frustrated by their complex interface, lack of customer support and the invasive permissions requested by these tools to user’s private data.

Their vision was to build an intuitive, affordable and privacy-focus mail merge application that would be accessible to beginners, experts and everyone in between. What they came up with was an add-on that prioritized privacy and efficiency above everything else, granting a complete set of features for a budget-friendly price.

Mailmeteor Pricing

One of the most affordable mail merge options on the market, Mailmeteor’s pricing starts at $8.99 per month or $49.99 per year. Mailmeteor offers a free version that you can use to send up to 150 emails per day for free. The premium version comes with all unlimited features. There are also options dedicated to teams and enterprise, with competitive pricing as you increase the number of seats in your license.

Mailmeteor Features

  • Send up to 2000 emails per day
  • Personalize emails
  • Preview emails before sending
  • Manage unsubscribes
  • Real-time emails tracking
  • Add attachments or personalized attachments
  • Send with email alias
  • Add CC or BCC recipients

  • Segment contacts & follow-ups
  • Import HTML templates

Yet Another Mail Merge (YAMM) logo

Type: Google add-on

One of the oldest mail merge tools, Yet Another Mail Merge – also known as YAMM – was built and first released circa 2010 by Google developer Romain Vialard. Since then, it was bought out by the Revevol group and it continues to go from strength to strength in offering a standard for mail merge quality.

YAMM Pricing

While it remained the most competitive add-on for long, YAMM recently updated its pricing in June 2021. With a starting price of $48 per year for Google Workspace users, Yet Another Mail Merge is now aligned with its most recent competitors. YAMM also offers dedicated pricing for gmail.com users and for teams. Learn more by comparing Yet Another Mail Merge vs Mailmeteor.

Type: Google Chrome extension

GMass is a mail merge extension, developed by Ajay Goel, an entrepreneur from Chicago. It’s a popular choice for many, with a long list of excellent features that hit the spot for both professional and individual users – though it can be tough to navigate and pricey for those on a budget.

GMass Pricing

GMass offers a freemium model like the previous mail merge extensions. The pricing is divided into two plans, a standard and a premium one. The premium plan will grant you access to sequences and follow-ups for $19.95 per month or $199 per year for an individual user. GMass offers pricing for teams too, it is the second most expensive option presented in this top mail merge for Gmail extensions list.

Mail Merge by Quicklution logo

Type: Google add-on

Founded in Malta by Andrew Dimech, Quicklution is a Google add-on creator, building extensions that are designed to streamline processes for businesses of all sizes. Their mail merge offers personalization, contact list linking with Google docs and other handy features, though it does spread itself a little thinly across those features, rather than focusing on getting the essentials right. The add-on itself has a lot of similarities with the Mail Merge Wizard in Microsoft Word.

Mail Merge Pricing

Quicklution opted for a classic pricing, with two options only. The starting price is $30 for a yearly plan and $80 for a lifetime license that will grant you access for life. Then, Quicklution offers discounts based on the number of users included in a license.

5. Mail Merge with Attachments

Mail Merge with Attachments logo

Type: Google add-on

This mail merge extension for Gmail is aimed at those looking to send mail merges with attachments, making it easier to send multiple documents, pictures, videos and more to multiple contacts. Though most mail merge extensions offer to attach documents to your emails now, the Mail Merge With Attachments extensions by Digital Inspiration (Labnol) remained an active player among the different mail merge services for Gmail.

Built by developer Amit Argawal from Agra India, Mail Merge With Attachments does its main job of mail merging with attachments well, but may fall short on the other parts that make up a good mail merge extension.

Mail Merge with Attachments Pricing

Mail Merge with Attachments pricing starts at $39 per year for individual users and $87 dollars for enterprise users. Though the pricing on their website is displayed per month, the license will be billed annually. Like other mail merge applications, there’s an option to buy a license for a G Suite domain as a whole.

Built by Romain Vialard who created YAMM, Mergo has a bright future ahead of it. The add-on is displayed as a sidebar only, which on the one hand is pretty convenient to use when you need to switch between your Google Sheets tabs, but might be limited in terms of user interface.

Mergo Pricing

The following entries on this list are business management suites that have mail merges – they aren’t used specifically for mail merging like the above extension are, but they all include mail merge for Gmail as a feature to some extent.

7. Streak

Streak logo

Type: Google Chrome extension

Streak is a CRM (customer relationship management) tool designed specifically for GMail by Aleen Mawani and Omar Ismail of San Francisco in 2011. Focused on using spreadsheets to connect with customers in a number of ways, Streak also includes a mail merge function – thought this function lacks the feature list and design focus of extensions that have a sole focus on mail merging.

Streak Pricing

Streak has a free version with a limited mail merge functionality for up to 50 recipients. Streak’s pricing is then divided in 3 tiers: Solo, Pro, Enterprise. The Solo Plan will let you mail merge up to 800 recipients maximum for $19 per month or $180 per year. If you want to send emails up to Gmail limits, then you will have to opt for the Pro plan starting at $59 per month or $588 per year. In short, Steak offers a mail merge feature as part of its CRM for Gmail, but it’s clearly not its core feature.
