Why customers choose GMass over YAMM

No Email Sending Limits
YAMM caps sends at 1,500/day even on paid plans. GMass breaks these limits with SMTP or multiple sending accounts, letting you scale your campaigns effortlessly.
Better Inbox Placement
YAMM provides no tools to optimize deliverability. GMass’s Spam Solver ensures your emails land in inboxes, not spam, increasing engagement and visibility.
Advanced Campaign Features
YAMM lacks essential tools like automated follow-ups and advanced tracking. GMass offers these and more, making your email campaigns smarter and more effective.

Sounds great, but I have a few doubts…

Is it really easy to set up GMass?
Absolutely! Install the Chrome extension, connect your Gmail account, and start sending campaigns in minutes — no steep learning curve required.
Does GMass work with Google Sheets like YAMM?
Yes, and better! GMass seamlessly integrates with Google Sheets, allowing you to send highly personalized email campaigns with dynamic fields and attachments, all within Gmail.
Can GMass really improve my deliverability?
Absolutely! GMass offers deliverability tools like Spam Solver to ensure your emails land in inboxes, not spam. YAMM lacks deliverability tools entirely.
Does GMass handle follow-ups and automation?
Yes! GMass lets you automate follow-ups that stop once your recipient replies. You can schedule follow-ups, trigger them based on no opens or clicks, and even push them manually. YAMM doesn’t offer this functionality.
