Mailmeteor vs YAMM

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.

YAMM is a mail merge tool for Gmail and Google Sheets, available on the web and as an extension. It sends personalized mass emails, with customization for subject lines, message content, links, images, attachments and CC/BCC fields. Its tracking covers opens, clicks, responses, bounces and unsubscribes in real time. Users can schedule mail merges and follow-up campaigns, and send personalized email notifications after Google Form submissions. YAMM supports CRM workflows including Salesforce and HubSpot. For HubSpot, it can import contacts into Google Sheets and log campaigns through a BCC address. The free plan allows 20 recipients per day for one user and includes best-effort support. Pro Gmail costs $25 a year for one user and allows 400 recipients per day; Pro Google Workspace costs $50 a year for one user and allows 1,500 per day for eligible accounts. Both Pro plans include priority support. YAMM says it does not store Gmail drafts, recipient addresses or spreadsheet content in its database, and does not sell personal data.
