Best AI Email Agents: FAQ

Can an AI email agent reply for me automatically?

+

Most tools draft replies for you to approve, which is the safer default. Some, like Jace and Lindy, can run rules that act on incoming email automatically, such as forwarding, labeling or creating tickets.

How much do AI email assistants cost?

+

Jace starts at $20 a month billed yearly, Shortwave at $30 per seat, Fyxer Pro at $37–$49 a month and Superhuman's Business plan with Mail at about $40 a month.

Is it safe to give an AI access to my email?

+

Reputable tools use OAuth access you can revoke and publish security certifications. Read the data policy, check whether your email is used for model training and avoid tools that cannot answer that clearly.

Do I need to switch email clients?

+

No. Fyxer, Lindy and Jace work with your existing Gmail or Outlook. Superhuman and Shortwave are full email clients you switch to.

How long before drafts sound like me?

+

Most assistants learn from your sent mail right away and improve over the first week or two as you edit their drafts.
