Which one to pick

Choose EmailBison if

  • You send hundreds of thousands of emails a month: one US$599 plan covers 500,000.
  • You want dedicated IPs on an isolated network as part of the plan.
  • Your security review needs SOC 2 Type II, GDPR or HIPAA reports from the vendor.
  • You want unlimited workspaces and teammates with no seat fees.

Choose Instantly if

  • You want to start small: Growth is US$47 a month billed monthly for 5,000 emails, with the API.
  • You want an official MCP server with campaign tools (199 tools on 25 Oct 2026).
  • You want a lead database in the same app (SuperSearch, on a separate credits plan).
  • You want published API rate limits: 100 requests a second and 6,000 a minute per workspace.

If neither fits: If LinkedIn is your main channel, a LinkedIn tool such as HeyReach or OutFlo fits better, and both can hand leads to an email sender. Whichever sender you pick, verify the list before you upload it.

Questions people ask

Is there a free platform for cold email outreach?

Neither has a free plan. Instantly gives a 14-day trial with no card; in the app on 25 Oct 2026 it allowed 1,250 emails a month and 250 uploaded contacts, and paid plans start at US$47 a month. EmailBison has no self-serve trial: you book a demo, and its one plan is US$599 a month.

Should you pay for a warmup tool?

Both include warmup. EmailBison's plan includes warm-up and bounce protection on an isolated network with dedicated IPs. Instantly includes unlimited mailboxes and warmup on every plan.

How many emails can be sent per day?

Both cap the month, and you set the daily pace. EmailBison covers 500,000 emails a month, with daily limits per sender that can be updated in bulk by API. Instantly allows 5,000 to 500,000 emails a month by plan; a new campaign had a daily limit of 30 emails in the app on 25 Oct 2026.

Does EmailBison have an API?

Yes, on its only plan. Each customer has a private instance, so the API base URL is the domain you log in on, and requests use a Bearer token from Settings > Developer API. Rate limits apply per key, but no figures are published.

Which one gives dedicated IPs?

EmailBison includes an isolated network with dedicated IPs in its US$599 plan. Instantly's Light Speed plan, US$358 a month billed monthly, adds private sending servers.
