Send E-Mail (old)

Deprecated. For new workflows use Send email: several recipients with Cc/Bcc, formatted text with signature, attachments, replies in the thread of a received email and drafts. Existing workflows with this step keep working; in the editor the step is marked Deprecated.

Send an outgoing email via SMTP.

What it does​

Connects to an SMTP server you configure (your company's mail server, a transactional service like SendGrid, or a generic provider), sends one email, and continues with the next step. The body and subject can be assembled by previous steps and pulled from memory.

What you configure​

FieldWhat it controlsRequiredNotes
SMTP hostAddress of the SMTP server.requiredExample: smtp.example.com or smtp.sendgrid.net.
SMTP portPort number.requiredTypically 587 (STARTTLS) or 465 (TLS).
SMTP userLogin for the SMTP server.requiredStored as a secured value.
SMTP passwordPassword / API key.requiredStored as a secured value.
FromSender address.requiredMust be allowed by your SMTP server. Many providers reject mismatches.
ToRecipient address.requiredA single address. Use a previous step to compute it from memory.
SubjectThe subject line.requiredCan be a literal value or a value pulled from memory.
BodyThe message body.requiredPlain text. For HTML, write the markup directly; the platform sends what you provide.

Example scenario​

Daily digest. A workflow runs on a cron schedule, builds a summary with an LLM, and ends with a Send E-Mail step that delivers the summary to a fixed distribution address.

Recommendations​

  • ✅ Use a dedicated SMTP account for the AI Kit. This makes it easy to spot which mails were sent by automations.
  • ✅ Set the From address to one your SMTP provider has authenticated (SPF/DKIM). Otherwise the mail lands in spam.
  • ✅ Keep the Subject short and informative. End-users often filter on it.
  • ⚠️ This integration sends one mail per execution. To send to multiple recipients, build a step that produces a list and run a sub-workflow per recipient, or use the To field with a comma-separated list if your SMTP server supports it.
  • ⚠️ HTML mails work, but every mail client renders them differently. Plain text is more robust.
  • ❌ Do not include large attachments. This integration does not support file attachments. Use a link to a file instead.
  • ❌ Do not store SMTP credentials in plain memory keys. Always use the secured-field types.
