Send email with SMTP
Point Tyrbo at any SMTP server — your workspace relay or custom domain — to send email from automations.
The SMTP integration sends email through any mail server you control — a workspace relay, your domain's mail host, or a transactional provider's SMTP endpoint. If you'd rather not manage SMTP details, the SendGrid integration does the same job with one API key.
Connection fields
| Field | What to enter |
| --- | --- |
| Host | Your SMTP server, e.g. smtp.gmail.com, smtp.office365.com |
| Email | The account to authenticate as (blank if your relay is open) |
| Password | The account's app password (blank if your relay is open) |
| Port | 587 (STARTTLS, most common) or 465 (implicit TLS) |
Gmail example
Host smtp.gmail.com, port 587, your Gmail address, and an app password
from
myaccount.google.com/apppasswords
(requires 2-step verification). Gmail rewrites the From address to the
authenticated account.
Notes
- The Send Email action lets each step set From, To, CC/BCC, subject, and a plain-text or HTML body.
- Sending domains need proper SPF/DKIM to land in inboxes — if you're setting those up for the first time, a provider like SendGrid handles it for you.
