Mailmeteor vs MailTag

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.

MailTag categorizes incoming messages inside an inbox you already use. It supports Gmail, Google Workspace, iCloud, Yahoo, Fastmail and IMAP mailboxes, and checks for new mail every five minutes. You can use its categories or describe custom ones in a single line. Existing mail can be labeled in one pass without deletion. Sender and domain controls let you unsubscribe, archive or apply a label rule, with confirmation and undo. MailTag says processing happens in memory on its own hardware in Germany, without sending email to outside services or storing message content. App passwords are encrypted with AES-256-GCM. Paid plans provide per-category webhooks for services such as Slack, Discord, Zapier, Make and n8n; Business adds an HTTP Triage API. The Free plan covers one mailbox and 100 labeled emails monthly. Solo is $6.59 a year, Pro $14.08 a year and Business $36.58 a year, each billed annually as listed. Seven days of Pro are available without a card, after which accounts move to Free unless upgraded.
