Cons of Mailmeteor

Mailmeteor doesn’t support SMTP sending, so you must follow Gmail or Google Workspace sending limits (500 and 2,000, respectively). Its free version lacks features and doesn’t include tools for setting up mail merge campaigns and adding attachments. The platform is also expensive compared to other cold email software.


GMass is a simple yet robust cold outreach tool for Gmail. It lets you send mass emails directly from the email platform and has tools like A/B testing and SMTP integration. However, it isn’t a full-fledged mail merge tool and has limited capabilities compared to other cold email software.

If you want an efficient email outreach platform with sales and multi-channel features, you can consider Yesware and Mailshake. Mailmeteor is also an excellent GMass alternative if you want robust contact management features and integrations.

However, if you want a full-fledged cold outreach software with diverse features, you can pick MailWizz. It’s self-hosted and contains all the essential email marketing features you’ll need for campaigns at a one-time licensing fee.
