weavmail is a command-line email client designed for AI agents. Use it to read, send, reply to, and organize emails

Setup

Install once before first use:

uv tool install weavmail

Configure an account (named default):

weavmail account config \
  --imap-host imap.example.com \
  --smtp-host smtp.example.com \
  --username [e-mail] \
  --password your-app-password \
  --addresses [e-mail]

--username and --password set both IMAP and SMTP credentials at once. The account name defaults to default and can be omitted from all subsequent commands.

Each option can be updated independently — only the options you pass are changed, everything else is preserved. For example, to update just the password:

weavmail account config --password new-password

--addresses is a comma-separated list of email addresses that are authorized as senders for this account (e.g. --addresses [e-mail],[e-mail]). All addresses listed here can be used as the --from address when sending mail.

To view the current configuration of an account, run account config without any options:

weavmail account config        # show default account
weavmail account config work   # show account named "work"

---

After Configuring an Account

After any account is configured, always run the following automatically:

weavmail mailbox

Inspect the output and identify the Sent and Trash folders (names vary by provider, e.g. Sent, Sent Messages, [Gmail]/Sent Mail, Trash, Deleted Messages, [Gmail]/Trash). Then save them to the account config:

weavmail account config --sent-mailbox "Sent" --trash-mailbox "Trash" --archive-mailbox "Archive"

To sync Spam (or other folders) in addition to INBOX, configure --sync-mailboxes:

weavmail account config --sync-mailboxes "INBOX,Spam"

All these fields are optional — if any cannot be identified with confidence, skip it. They do not affect other functionality when unset.

---

Sync Mail

Fetch the latest emails and save them as local Markdown files. Sync uses all configured accounts and each account's sync_mailboxes config (default: INBOX):

weavmail sync

Options:

• --limit N — number of most-recent messages to fetch per mailbox (default: 10)

To include Spam (or other folders) in the default sync, run:

weavmail account config --sync-mailboxes "INBOX,Spam"

Each email is saved to ./mails/<account>_<mailbox>/<uid>.md with YAML front matter:

---
uid: "12345"
account: default
mailbox: INBOX
subject: Hello there
from: [e-mail]
to:
- [e-mail]
cc: []
date: "01 Jan 2026 12:00:00 +0000"
flags: []
---

Mail body here...

Always sync before reading mail. After syncing, read .md files directly — the body starts after the second ---.

---

List Mailboxes

List all available IMAP folders for the account:

weavmail mailbox

Use this to discover exact folder names before syncing a non-INBOX mailbox. Folder names are case-sensitive.

---

Move a Mail

Move an email to another folder, then automatically sync the source mailbox:

weavmail move mails/default_INBOX/12345.md "Archive"

The source mailbox is synced after the move — the local file will be deleted automatically.

To delete a mail, move it to the Trash folder. The exact name varies by provider (e.g. Trash, Deleted Messages, [Gmail]/Trash). Use weavmail mailbox to find the correct name first.

---

Trash a Mail

Move one or more emails to the account's trash mailbox, then automatically sync the source mailbox:

weavmail trash mails/default_INBOX/12345.md
weavmail trash mails/default_INBOX/12345.md mails/default_INBOX/67890.md

Multiple MAIL_FILE arguments can be passed for batch operations. The trash mailbox is read from each mail's account --trash-mailbox configuration. An error is raised if --trash-mailbox is not configured for the account.

The source mailbox is synced after the move — the local file will be deleted automatically.

---

Archive a Mail

Move one or more emails to the account's archive mailbox, then automatically sync the source mailbox:

weavmail archive mails/default_INBOX/12345.md
weavmail archive mails/default_INBOX/12345.md mails/default_INBOX/67890.md

Multiple MAIL_FILE arguments can be passed for batch operations. The archive mailbox is read from each mail's account --archive-mailbox configuration. An error is raised if --archive-mailbox is not configured for the account.

The source mailbox is synced after the move — the local file will be deleted automatically.

---

Send a Mail

Write the body to a file, then send:

cat > /tmp/body.txt << 'EOF'
Your message here.
EOF

weavmail send \
  --to [e-mail] \
  --subject "Hello" \
  --content /tmp/body.txt

--to, --cc, and --bcc are all repeatable for multiple recipients. --from defaults to the first configured address.

---

Reply to a Mail

weavmail send \
  --reply mails/default_INBOX/12345.md \
  --content /tmp/reply.txt

In reply mode, subject, to, and from are all inferred from the original mail's front matter. The original body is quoted and appended. In-Reply-To and References headers are set automatically. Override any of them with explicit options if needed.

---

Notes

• Never guess UIDs. Always sync first, then reference files from the output.
• Mailbox names are case-sensitive. Use weavmail mailbox to list exact names.
• The mailbox field in front matter stores the original unescaped name (e.g. INBOX/Sent); the directory path uses _ as a separator.
• Front matter is authoritative for metadata — always read it from the .md file.
• All commands support --help for full option details, e.g. weavmail sync --help.

---

Multiple Accounts

Configure additional accounts by providing a name:

weavmail account config work \
  --imap-host imap.work.com \
  --smtp-host smtp.work.com \
  --username [e-mail] \
  --password your-password \
  --addresses [e-mail]

Pass --account to target a specific account where supported:

weavmail mailbox --account work
weavmail send --account work --to [e-mail] --subject "Hi" --content /tmp/body.txt

weavmail sync always syncs all configured accounts using each account's sync_mailboxes config.

For move and send --reply, the account is read from the mail file's front matter — you may pass --account as a safeguard: if it doesn't match the account in the front matter, the command will exit with an error. For trash and archive, the account is always read from each mail file's front matter (no --account option).
