01 Deliverability
Shared-IP tools broke in 2026. Yours will not.
When Gmail and Outlook tightened bulk-sender rules, platforms on shared IP pools lost a large slice of their deliverability overnight. AiOOutreach never puts you on a shared pool.
Your reputation
Send on domains and accounts you own.
Warm-up ramp
Grow volume gradually and automatically.
Account rotation
Spread sends across every connected inbox.
Encrypted keys
Credentials encrypted at rest, always.
02How it works
Three steps to your first send.
Bring your leads
Import your list with any custom fields. Every column becomes a merge variable you personalize on.
Bring your accounts
Connect Mailjet, Mailgun, SendGrid, Brevo, Outlook, Gmail or raw SMTP. Your keys, encrypted, verified live.
Connect and schedule
Build a drip, set send windows and caps, hit start. Warm-up and follow-ups run on their own.
03Senders
Connect the senders you already have.
20 integrations and counting. Bring your own keys, rotate across as many inboxes as you like, and keep your sender reputation entirely yours.

07FAQ
Questions, answered.
Is AiOOutreach really free?
Yes. It is in beta and everything is completely free right now. You only ever pay your own email provider for what you send.
Can I use my own SMTP, Outlook or Gmail?
Yes. Connect any SMTP mailbox, including Outlook/Office365, Gmail with an app password and Zoho, or plug in an ESP like Mailjet, Mailgun, SendGrid or Brevo.
Does AiOOutreach use shared IPs?
No. Every email sends through your own connected account, so your sender reputation is yours to control, not a shared pool that can get you throttled.
Which providers can I connect?
Mailjet, Mailgun, SendGrid, Brevo, MailerLite, and any SMTP mailbox. Connect as many as you like and rotate between them.
Are my keys safe?
Yes. Every credential is end-to-end encrypted at rest and verified with a live test the moment you connect. Keys are never shown back in the dashboard.
Can I run it with AI?
Yes. AiOOutreach exposes an MCP interface, so an AI assistant can create campaigns, import leads, schedule sends and check delivery status for you.
