EmailBison review: a private sequencer instance for $599 a month, and what the full setup costs

EmailBison runs your cold email on your own single-tenant instance with dedicated IPs, a private warmup pool and white label, for $599 a month and 500,000 emails, bought through a demo. It sells no mailboxes, so at 5,000 emails a day the setup is $1,142 a month with our mailboxes. Outreach2day does the same email-only job with mailboxes, warmup and a sequencer in one bill for $543.

Who EmailBison fits

Pick EmailBison if

  • You send 500,000+ emails a month and want your own instance with dedicated IPs
  • You run an agency and want a white-labeled tool for clients
  • You need SSO, SCIM or a SOC 2 report from your sequencer
  • You already buy mailboxes from one of its approved SMTP vendors

Look elsewhere if

  • You send under 5,000 emails a day and the $599 is mostly unused capacity
  • You want to start without a demo call or see a trial first
  • You want EmailBison's warmup on SMTP mailboxes from a vendor outside its approved list
  • You want mailboxes and the sequencer from one vendor

What EmailBison is

EmailBison is a cold email sequencer for agencies and high-volume teams. Each customer gets an isolated instance on its own subdomain, branded with its logo and colours, with at least two dedicated IPs and more added as volume grows. Campaigns, a master inbox for replies, unlimited workspaces and teammates, a REST API with webhooks and an MCP server come with it.

You bring the mailboxes: Google, Microsoft or custom SMTP accounts, mixed in one campaign. Custom SMTP accounts come in by CSV, 500 per upload. EmailBison's help center now keeps custom SMTP accounts from vendors outside its approved list (Winnr, MissionInbox, ScaledMail SMTP, InboxedUp, Lunatro) out of its warmup network; they still connect and send.

Many pages ranking for "email bison" quote $499 or invent cheaper tiers. EmailBison's pricing page lists one plan at $599, and its help center adds the overage and B2C prices below.

Cold email sequencer run as a single-tenant, white-labeled instance with dedicated IPs, private warmup and a master inbox, sold by demo source (opens the vendor's page in a new tab)

EmailBison pricing

List prices from EmailBison's pricing page, checked . Taxes and card fees excluded.

One plan: $599 a month for 500,000 emails with unlimited leads, workspaces and teammates. Above that, each extra 250,000 emails is $250 a month, with bulk discounts above 2,000,000. When the monthly cap is reached, sending stops until you upgrade.

Sending to personal addresses (Gmail, Outlook.com and the like) needs a separate instance at $249 a month with 250,000 sends; B2C sending is off by default. No annual price, trial or refund policy is published, and access starts with a demo call.

The plan is priced for volume: 22,000 emails a month (1,000 a day) use under 5% of it. Below about 5,000 emails a day, the $599 is mostly paying for capacity you do not use.

What a full EmailBison setup costs a month

The cold email sequencer plan the volume needs, plus mailboxes and domains, at 1,000, 5,000 and 10,000 cold emails a day.

25 cold emails per mailbox a day and 5 mailboxes per domain: 1,000 a day = 40 mailboxes, 8 domains, 22,000 emails a month; 5,000 a day = 200 mailboxes, 40 domains, 110,000 emails a month; 10,000 a day = 400 mailboxes, 80 domains, 220,000 emails a month (22 sending days). Monthly list prices on monthly billing; .com domains at $13 a year spread over 12 months.

EmailBison's $599 is the same at every volume in the table, so the mailboxes decide the rest. With Outreach2day mailboxes and domains the setup is about $708 a month at 1,000 emails a day, $1,142 at 5,000 and $1,686 at 10,000.

Outreach2day all-in replaces the EmailBison plan with our own sequencer: about $109, $543 and $1,087 a month at the same volumes, warmup included. From 1,000 mailboxes we quote a volume price below every vendor list price in our comparisons on a call.

EmailBison makes sense when you need what we do not sell: a white-labeled instance for clients, dedicated sending IPs, SSO and SCIM. Teams that only need to send email-only campaigns from warm mailboxes pay less with us.

In detail

Adding Outreach2day mailboxes to EmailBison

Export the mailboxes from Outreach2day as a CSV (Mailboxes, Export, Download CSV), then in EmailBison open Email Accounts, Connect email account, Bulk Upload Custom Provider, and put our values under the headers of its sample file. The fields, ports and fixes are in the EmailBison integration guide.

Warmup for these mailboxes keeps running in Outreach2day, included in the $2.50, which matters here: EmailBison keeps custom SMTP accounts from vendors outside its approved list out of its own warmup network.

API, MCP and integrations

The REST API uses bearer keys per workspace, allows 3,000 calls a minute per key, and creates sender accounts one by one or from a CSV. EmailBison runs an MCP server whose address you find in the app under Settings, Integrations; it is not published.

Clay and EmailGuard connect natively, HubSpot and Salesforce through OutboundSync, and HeyReach and Aimfox take non-responders for LinkedIn steps. Placement tests through EmailGuard need a paid EmailGuard plan. Outreach2day's MCP server is public and covers domains, mailboxes, warmup, campaigns and replies.
