Once connected, Claude can:
- Read and search your mailboxes: list conversations by folder, open a whole conversation and find messages by person, subject or text.
- Write drafts and reply drafts that wait in Drafts for you to review and send.
- Send, reply and send a draft, once you have turned sending on for that mailbox, and check whether each message was delivered.
- Mark messages read or unread, star them and move them between inbox, archive, trash and spam.
- Start domain setup and show how your domains are paid for. Domains, DNS, team access and agent permissions stay yours, in the dashboard.
The LotsMail dashboard does the whole job too: a full inbox on every device, plus domains, mailboxes, team and agent permissions. Your agent for speed, the dashboard for control.

Can my agent send email without me?
Only if you turn on sending for that mailbox. Sending is off until you do. With read or draft access your agent can search, read and write drafts that wait in Drafts for you to review and send.
Which mailboxes can my agent open?
Only the mailboxes you can open yourself. For each one you choose what agents may do: read and search, write drafts, or send. Owners do not get private mailboxes by default.
Can I limit who my agent emails?
Yes. A mailbox can be restricted to a list of addresses it may send to, and any other recipient refuses the whole send. Only a workspace owner or admin changes restrictions, in the dashboard.
Can my agent change my domain or DNS?
No. It can start domain setup, which gives you the steps and the dashboard link. Domains, DNS, billing, team access and agent permissions stay with you, in the dashboard.
