Pricing summarised in October 2026 and not re-checked since. Vendors change plans often, so confirm current pricing with EmailBison before you budget.

Security and governance

Outreach tools hold mailbox credentials and prospect data. Use SSO where offered, connect mailboxes with OAuth rather than passwords, restrict who can export lists, and keep opt-out and suppression lists synced with your CRM to meet anti-spam rules.

How we would roll it out

  1. Set up domains and warm-up firstSeparate sending domains from your main domain.
  2. Start with one tightly targeted sequenceMeasure reply and meeting rates before adding volume.
  3. Sync replies and opt-outs to the CRMSo nobody is contacted after saying no.
