AI Email Marketing Automation Tool

Can I connect unlimited email accounts to Mails.ai?
Yes. You can connect unlimited email accounts from any provider. We don’t charge per inbox, so you can connect as many accounts as you need.
Can I upload unlimited contacts to Mails.ai?
Unlimited Uploaded Contacts are included starting with the Startup plan and are also included on Growth and Pro. The Forever Free plan does not specify this capability.
Is there a daily sending limit on Mails.ai?
There is no daily limit on emails. Sending is governed by the number of new unique active contacts you outreach to in a given month.
How many steps can I create in a campaign sequence?
Unlimited. You can create as many sequence steps as you want.
What are Active Contacts and how are they counted?
Active Contacts are unique email IDs you connected with in a month. The counter resets each month. Credits are counted from the first email of each contact, and in the Pro plan you can have unlimited Active Contacts.
What is Inbox Rotation and how does it affect deliverability?
Inbox Rotation uses smart sender rotation across your connected accounts to increase inbox delivery and reduce spam flags, helping emails reach more recipients’ inboxes.
What are Mailbox Warmup and Campaign Warmup?
Mailbox Warmup gradually sends normal emails to accounts in a warmup pool to build a positive sender reputation and improve deliverability. Campaign Warmup trains algorithms by sending campaign emails and marking them as not spam to reduce content-based spam detection. Used together, they aim to maximize deliverability and replies.

Email Verifier is included starting with the Startup plan and is available on Growth and Pro plans. There is also a new Background Email Verifier that runs in the background, with verification credits included for free and refreshed monthly.
What is Background Email Verifier and how does it work?
Background Email Verifier runs in the background while you work. You can import a list, start verification, and check back later—the system continues verifying in the background and marks emails as Valid or Invalid. Verification credits are included for free and refreshed monthly.
