Frequently Asked Questions
Everything you need to know about switching from GMass.
Why is OutSends a better alternative to GMass?
GMass charges per individual inbox and locks follow-up sequences behind its $35/mo Premium plan. OutSends gives you unlimited sequences, campaigns, and automations from day one, connecting 15 senders for only $19/mo, with built-in multi-provider warmup and AI Spintax.
Does GMass include email warmup?
GMass historically had an internal warmup tool that experienced disruptions due to Google policy updates. OutSends provides a modern, dedicated multi-provider warmup engine that simulates realistic human replies across Gmail, Zoho, and SMTP to ensure maximum deliverability.
