What tools does Mission Inbox integrate with?

Mission Inbox can integrate with most sales engagement platforms, cold email sequencers, CRMs and workflow tools, as long as they support SMTP and IMAP connection. If the tool can send and sync through connected mailboxes, Mission Inbox can usually sit underneath it as the sending infrastructure.

Does Mission Inbox replace my CRM or outreach tool?

No. Mission Inbox does not replace tools like HubSpot, Salesforce, Outreach, Salesloft, Smartlead, Instantly or Apollo. Your existing software manages the workflow. Mission Inbox supports the sending infrastructure behind it.

Why connect Mission Inbox to my existing software?

Most sales, CRM and outreach tools manage contacts, campaigns, sequences or workflows. Mission Inbox gives your team more control over the email sending layer, including domains, mailboxes, routing, monitoring and dedicated sending environments.

Can I use Mission Inbox with cold email tools?

Yes. Mission Inbox can work with almost any cold email sequencer that supports SMTP and IMAP. Your sequencer manages campaigns, replies and follow-ups. Mission Inbox supports the sending infrastructure behind it, including domains, mailboxes, routing and monitoring.

Can I use Mission Inbox with CRM workflows?

Yes. CRM emails such as sales follow-ups, lead nurture, account updates and customer workflow emails can be routed through Mission Inbox where the setup supports it.

Can different tools use different sending setups?

Yes. Teams can separate sending by tool, department, campaign, domain, mailbox or client. This is useful when you do not want every type of email relying on the same sending environment.

Do I need a developer to connect an integration?

Usually, no. Most cold email sequencers and sales tools can connect through SMTP and IMAP settings. API-based setups may need developer or admin support, but standard mailbox-based integrations are usually handled through the tool's sending account settings.

Which integration should I choose?

Choose the integration based on the software your team already uses to manage email workflows. For example, use HubSpot or Salesforce for CRM workflows, Outreach or Salesloft for sales engagement, and Smartlead or Instantly for cold outreach.
