G Merge Plus vs Mailmeteor

G Merge Plus creates personalized documents and email campaigns from Google Sheets. It can combine a sheet with a document template to generate PDFs, Google Docs, or Sheets, then send personalized messages from the user's Gmail address with generated documents attached. Merges can be queued for later or scheduled to recur. Delivery and open reports appear in the Sheet, and the marketing section also describes click tracking. Campaigns can include one-click unsubscribe; opt-outs are recorded in the Sheet and skipped on the next send. Reusable email and document templates are available, with shared templates listed for the Team plan. The workflow includes Gmail, Google Sheets, Google Docs, and Google Drive. G Merge Plus uses Google Sign In and says it does not access Gmail passwords. It says email and generated document contents are not stored, and generated files are kept in the user's Drive. The free plan has unlimited mail merge but no document merge or tracking, and is subject to Google limitations. Pro is $72 a year; Team is $480 a year.

Mailmeteor runs personalized email campaigns and helps manage replies from Gmail, Outlook, and other tools. Mail merges can start from Gmail, Outlook, Excel, Google Sheets, or Google Docs. Campaign features include tracking, scheduling, templates, attachments, audience segmentation, unsubscribe management, and conditional follow-ups. Its AI assistant sorts emails, drafts replies in the user’s tone, and rewrites, improves, or shortens messages, but the assistant is currently available only for Gmail. Mailmeteor connects with Zapier and Google Sheets automations, and sent messages can be logged in Salesforce or HubSpot through a CRM BCC address. The free Hobby plan includes 500 emails per month. Paid plans start at $5.99 per user per month, with listed daily and monthly limits by tier. Mailmeteor says it requests only essential sending permissions and keeps customer data in the Google Spreadsheet by design.
