Mail

e9e is AI cold email software with automatic warm-up and deliverability protection. Echo writes each recipient their own email, sent from your Gmail or Outlook.

Connect Gmail or Outlook

Once you connect your account, all your correspondence gathers in a single inbox, and your cold email campaigns run from there.

Not a template, a message made for the person

Echo writes a separate, natural email for every recipient, so instead of blasting the same template to everyone, genuinely personalized messages go out.

Not a template, a truly personal email

e9e is AI cold email software with automatic warm-up and deliverability protection built in. Cold email succeeds or fails on personalization, but writing a separate email for everyone simply does not scale. Echo takes this on: it reads the context for each recipient, writes a natural, personalized message and sends it from your Gmail or Outlook account.

On the deliverability side, warm-up and volume control are automatic: SPF, DKIM and DMARC records are monitored, daily sending volume ramps up gradually and bounce and reply signals are tracked. Your emails stay in the inbox instead of the spam folder, replies are collected in one place and follow-up sequences move forward on their own.
