BetterMerge

BetterMerge is a mail merge tool for Gmail and Google Sheets. It sends personalized emails one by one from the user's own Gmail or Google Workspace account, taking names and other fields from a Google Sheet, and it tracks opens, clicks and unsubscribes in real time. The home page describes the purpose as "Send outreach, newsletters, and announcements as personal one-to-one emails from your own Gmail." It is built, in the site's words, "for small businesses and professionals."

The product was previously called Mailway Mail Merge; the home page carries the line "Formerly Mailway Mail Merge." It is listed on the Google Workspace Marketplace, where the site reports a 4.9 out of 5 rating "across 142 Marketplace reviews" and "19,000+ installs." BetterMerge states that it is an independent product not affiliated with Google.

How a campaign works

The home page lays out four steps.

1. Prepare the list. Recipients go into a Google Sheet "with column headers in the top row." BetterMerge "reads your data directly," so nothing has to be exported first.
2. Write the email. The message is composed in Gmail, using merge tags like {{First Name}} to personalize each copy. The site says drafts are written in "Gmail's familiar editor" and sent "with one click."
3. Send or schedule. A campaign can go out at once or be scheduled, with daily limits and delivery windows "to stay within Gmail's guidelines."
4. Track results. Opens, clicks and unsubscribes appear in the Google Sheet as the campaign runs.

Because every message leaves from the sender's own address, recipients see a normal personal email rather than a bulk newsletter from a sending service. That is what makes the tool useful for cold outreach, sales follow-ups and announcements to a known group.

What a sender gets

The feature list on the home page is specific:

• Personalization. Merge tags from the spreadsheet can personalize "subject lines, bodies, links, images, and attachments for each recipient."
• Rich Template Editor. Emails can be composed "with our WYSIWYG or HTML editor," with a preview of how the message will look.
• Attachments. Standard files such as PDFs, Word documents and Excel files can be attached to everyone, or each recipient can get a personalized attachment from Google Drive, including Docs, Sheets, PDFs, Word, Excel and PowerPoint files.
• Contact Segmentation. Users can "Filter recipients using Google Sheets data, exclude hidden rows, and target follow-ups based on opens and clicks."
• CC and BCC. Recipients can be added in CC or BCC "to integrate with CRMs, team inboxes, or third-party tools."
• Preview Before Sending. Each individual email can be reviewed to check personalization and formatting for every recipient.
• Schedule Campaigns. Delivery can be set for a future date and time, which the site notes helps with "timing across time zones."
• Delivery Automation. Senders can "Set daily sending limits, choose weekdays, define time ranges, and add delays between emails for natural delivery."
• Real-Time Tracking. Opens, link clicks and unsubscribes are tracked from the Google Sheet. A second line adds that "Opens, clicks, bounces, and unsubscribes stream into your dashboard and your sheet as they happen," with no refresh and no CSV exports.
• Unsubscribe Links. The site says users can "Add one-click unsubscribe links to stay compliant with CAN-SPAM and other anti-spam regulations automatically."

BetterMerge runs in two places. Campaigns can be managed "from the Google Sheets add-on or the full web dashboard," so a user who lives in spreadsheets never has to leave Sheets, while a user who prefers a dashboard gets one. The glossary page describes installing the add-on through Extensions, then Add-ons, then Get add-ons in Google Sheets, and opening it from the Extensions menu.

Sending limits

BetterMerge sends through Gmail, so Google's own quotas apply. The home page states "Send up to 500 emails/day on Gmail or 2,000/day on Google Workspace. We respect Google's limits to keep your account safe." The glossary adds that both account types allow 500 recipients per message and that the daily limit on a free Gmail account is a rolling 24-hour limit. It also explains what BetterMerge adds over Gmail's built-in mail merge on paid Workspace plans: "personalized subject lines and attachments, scheduling, sending windows, and open and click tracking written back to your sheet," and it notes that BetterMerge "also works on free Gmail accounts."

Privacy

Privacy is one of the main points on the home page. The top banner promises send-only Gmail access and says the company never reads your inbox, and the site says "BetterMerge requests only the Gmail permissions needed to send." Conversations stay private because the tool never asks for full mailbox access. The Privacy-first Design section adds "Your data stays in your Google account."

Free plan and pricing

BetterMerge has a real free plan: "Free plan includes 50 emails/day. No credit card required." The site describes the paid plans as the way to get higher daily quotas. On paid plans, the home page says "Plans are priced for small businesses, with higher daily quotas at each tier than comparably priced alternatives." Paid plan prices sit on a separate pricing page. The site promises "Setup in under 5 minutes."

Support and resources

The FAQ covers how to get support, and the site has a contact page, documentation, a changelog, a status page and a 3-minute video tutorial. It also offers free tools, including an email spam checker, DNS lookups and an AI email writer, plus an email marketing glossary. The glossary's deliverability advice covers authenticating a domain with SPF and DKIM, warming up gradually and keeping bounce rates under 5%.

Who BetterMerge suits

BetterMerge fits people who already work in Gmail and Google Sheets and want to send personalized emails that look like they were written one at a time: a freelancer pitching clients, a small sales team following up with leads, a recruiter contacting candidates, or an office sending announcements with personal attachments. The free plan is enough to try it on small sends, and the send-only permission will appeal to anyone wary of giving a tool full inbox access.

It is less suited to large newsletter programs, since sending is capped by Gmail's daily quotas, and the pages describe no signup forms, landing pages or multi-step automated journeys.
