1. When does auto-send make sense?
- HR: auto-email interview invites to candidates.
- E-commerce: bulk-contact influencers about sample shipments.
- Admin: send official approval results company-wide.
2. Which mailboxes are supported?
- DingTalk Mail
- Outlook
- 163 (NetEase)
- QQ Mail
- Note: bulk-receive is not supported.
2. Setup
🍤 DingTalk and Outlook support one-click OAuth — sign in and send. 163 and QQ require an SMTP authorization code.
2.1 DingTalk / Outlook one-click OAuth
- Add the Outlook node and create a new credential.
- Credential name: any text or numbers up to 20 characters — used to identify the authorized mailbox.
- Click confirm — you’ll be redirected to Microsoft sign-in to authorize. Once done, pick the credential to use in the node.
2.2 163 / QQ — get an SMTP authorization code
- Sign in to your 163 mailbox.
- Go to Settings → SMTP service → Enable.
- Generate the authorization code (3) and save it immediately (it disappears once you close the page).
- Paste the code into Credential management (3) in the automation editor.
- Step-by-step guide for getting the SMTP authorization code:
2.2 Step 2: configure the send action
- Fill in the email credential: paste the credential code into the automation.
-
Compose the email:
- Subject: type directly or use a dynamic variable.
- Recipients: variables recommended (multi-recipient supported).
- Body: write per your business needs.
-
Critical settings:
- Encoding: pick UTF-8 (cannot be empty).
- Attachments: leave blank (only attachment links are output today, not the file itself).
- All fields: do not leave blank — empty fields cause the run to fail.
3. FAQ
- Run failed with “remote service error” — what now?
- Re-check that subject, recipients, body, and encoding are filled, and that the attachment field is empty.
