The GMass alternative for tracking, not mass sending.
GMass turns Gmail into a mail-merge and cold-email machine — large campaigns, follow-up automation, and, on its newer plans, a dedicated sending server that pushes past Gmail's limits. Maildriply takes the opposite stance: stay inside your normal Gmail sending, and focus on honest open and click tracking.
- Built for high-volume cold email, with paid plans from roughly $25–$60/month for the sending features.
- Newer tiers route through a dedicated cold-email sending server to exceed Gmail's limits — more than a tracker needs.
- Aimed at mass outreach, so the tracking is wrapped in campaign and automation tooling.
- Tracking-first and free during early access — no campaign engine to pay for.
- Your mail stays within normal Gmail sending; we never bolt on a separate relay.
- Opens are bot-filtered and deduped, clicks use HMAC-signed redirects — accuracy over volume.

Switching from GMass
Is Maildriply a cold-email tool like GMass?
No. GMass is built for high-volume mail merge and cold outreach. Maildriply is a focused tracker for the emails you already send from Gmail, with templates and mail-merge for light personalization — not mass campaigns.
Does Maildriply send through a separate server like GMass's cold-email plans?
No. GMass's newer plans add a dedicated sending server to exceed Gmail limits. Maildriply always sends through your own Gmail account via the Gmail API — no relay, so your sender reputation stays yours.
How many emails can I track on Maildriply?
Early access includes 500 tracked sends per month per connected Gmail account. That's tuned for real, personal sending rather than the bulk volumes GMass targets.
