EmailBison

EmailBison is a cold email sequencing platform that runs on dedicated infrastructure. Instead of sharing servers with other senders, each customer gets isolated virtual private clouds with static egress IPs and multiple dedicated sending IP pools, which protects deliverability from other people's behaviour.

On top of that sits a full sequencer: multi-step sequences, step-level A/B testing, reply-triggered follow-ups and a Master Inbox for handling replies. Lead storage is unlimited with custom variables, and there are no per-seat fees, with unlimited team members and unlimited isolated workspaces, which suits agencies separating client data. Native integrations include Clay, EmailGuard, HubSpot and Salesforce, with n8n and Make support.

EmailBison is aimed at agencies and go-to-market teams sending high volumes, and access is invite-based through a sales call rather than self-serve signup.

It uses a single flat-rate plan, currently $599 a month, which includes up to 500,000 emails a month with warm-up, API access and support bundled in. There is no free trial.
