ccstringoptionalCarbon copy recipient(s). Separate multiple addresses with commas.
bccstringoptionalBlind carbon copy recipient(s). Separate multiple addresses with commas. BCC addresses are hidden from other recipients.
subjectstringrequiredEmail subject line.
textstringoptionalPlain text email body. At least one of 'Plain Text Body' or 'HTML Body' must be provided. If both are set, email clients choose which to display.
htmlstringoptionalHTML email body. Takes priority over plain text in most email clients. Example: '<h1>Hello</h1><p>This is a test.</p>'
replyTostringoptionalReply-to email address. When recipients reply, their response goes to this address instead of the sender.
attachmentsarrayoptionalFile attachments as base64-encoded objects. Each item needs 'filename' (string) and 'data' (base64 string). Example: [{"filename": "report.pdf", "data": "base64data..."}]
smtpHoststringrequiredSMTP server hostname. Examples: smtp.gmail.com, smtp.office365.com, smtp.mail.yahoo.com, smtp.mailgun.org, smtp.sendgrid.net
smtpPortintegeroptionalSMTP server port. Use 587 for STARTTLS (recommended), 465 for SSL/TLS, or 25 for unencrypted.
smtpUserstringrequiredSMTP login username. Usually your full email address. For SendGrid, use 'apikey' as the username.
smtpPasswordstringrequiredSMTP login password. For Gmail, use an App Password (Google Account > Security > App Passwords). For SendGrid/Mailgun, use your API key.
useTlsbooleanoptionalEnable TLS encryption. Port 587 uses STARTTLS, port 465 uses direct SSL. Recommended: always keep enabled.

SMTP Email Sender for Workflow Notifications

Most scraping and automation pipelines end with "now tell someone." This actor is that last step: point it at your own SMTP account — Gmail, Outlook, Yahoo, SendGrid, Mailgun, Amazon SES, or any other mail server — and it sends one email on your behalf. Trigger it standalone, chain it after another actor finishes, or call it from a webhook so a run's results land in an inbox automatically.

What this actor does

  • Sends a single email per run through the SMTP credentials you provide
  • Supports plain text, HTML, or both in the same message
  • Adds CC, BCC, and Reply-To addresses, with multiple recipients per field
  • Attaches files you supply as base64-encoded content
  • Sends from the address in smtpUser, so the SMTP username should be the mailbox you want the email to come from
  • Reports whether CC, BCC, or a Reply-To address were used, alongside the message's own delivery details

Output per sent email

  • status — delivery status (sent)
  • to — recipient address(es)
  • cc — CC address(es); an empty string when none were set
  • bcc — BCC address(es); an empty string when none were set
  • subject — email subject line
  • replyTo — reply-to address; an empty string when not set
  • hasHtml — whether an HTML body was included
  • hasText — whether a plain text body was included
  • attachmentCount — number of attachments supplied in attachments (an entry with invalid or empty data is skipped from the message but still counted here)
  • smtpHost — SMTP server used to send the message
  • smtpPort — SMTP port used
  • sentFrom — sender address (your SMTP username)
  • messageId — the message's Message-ID header; currently an empty string, because the actor doesn't assign one before sending
  • sentAt — ISO 8601 timestamp of when the message was sent

A record is written only when the SMTP server accepts the message. If validation or sending fails, the run fails with the reason in its status message and the dataset stays empty.

Input

Field Type Default Description
to string – Recipient address(es), comma-separated. Required.
cc string – CC address(es), comma-separated.
bcc string – BCC address(es), comma-separated.
subject string – Email subject line. Required.
text string – Plain text body. At least one of text or html is required.
html string – HTML body. At least one of text or html is required.
replyTo string – Address replies should go to, if different from the sender.
attachments array – Files to attach, each as { "filename": ..., "data": "<base64>" }.
smtpHost string – SMTP server hostname (e.g. smtp.gmail.com). Required.
smtpPort integer 587 SMTP server port: 587 for STARTTLS, 465 for direct SSL, or any other port your server uses.
smtpUser string – SMTP login username. Required.
smtpPassword string – SMTP login password or API key. Required; stored encrypted.
useTls boolean true Encrypt the connection: direct SSL on port 465, STARTTLS on every other port. Turn off only for servers that accept unencrypted connections (e.g. some port 25 relays).

Example: plain report email via Gmail

{
  "to": "team@example.com",
  "subject": "Daily scrape complete",
  "text": "The nightly run finished with 1,204 new records.",
  "smtpHost": "smtp.gmail.com",
  "smtpPort": 587,
  "smtpUser": "you@gmail.com",
  "smtpPassword": "your-app-password",
  "useTls": true
}

Example: HTML report with an attachment and CC via Mailgun

{
  "to": "alice@example.com, bob@example.com",
  "cc": "manager@example.com",
  "subject": "Weekly Export",
  "html": "<h1>Weekly Export</h1><p>See the attached CSV.</p>",
  "attachments": [
    { "filename": "export.csv", "data": "bmFtZSxjb3VudA0KZm9vLDEyMw==" }
  ],
  "smtpHost": "smtp.mailgun.org",
  "smtpPort": 587,
  "smtpUser": "reports@mg.example.com",
  "smtpPassword": "your-mailgun-smtp-password"
}

Example: alert with a custom Reply-To via Outlook / Office 365

{
  "to": "oncall@example.com",
  "subject": "Threshold exceeded",
  "html": "<p>Error rate crossed 5% in the last hour.</p>",
  "replyTo": "alerts@example.com",
  "smtpHost": "smtp.office365.com",
  "smtpPort": 587,
  "smtpUser": "monitoring@yourcompany.com",
  "smtpPassword": "your-mailbox-password"
}

Use cases

  • Run completion alerts — email a summary the moment a scraper or data pipeline finishes
  • Scheduled reports — attach a CSV or JSON export and send it on a recurring schedule
  • Threshold monitoring — fire an email when a webhook detects a condition worth flagging
  • Team notifications — CC or BCC a distribution list whenever a workflow step completes
  • Lightweight transactional mail — confirmations, digests, or reminders from a no-code pipeline

FAQ

Which mail providers work with this actor? Any provider that exposes SMTP, including Gmail, Outlook/Office 365, Yahoo Mail, SendGrid, Mailgun, and Amazon SES. You supply the host, port, username, and password for your own account. Because the From address is always your SMTP username, providers whose username is an email address (Gmail, Outlook, Yahoo, Mailgun) work out of the box. SendGrid (username apikey) and Amazon SES (an access-key style username) will usually reject the message, since that username isn't a verified sender address.

Do I need an app password for Gmail? Yes, if your Google account has 2-factor authentication enabled (recommended). Generate one under Google Account > Security > App Passwords and use it as smtpPassword.

Can I send to several people at once? Yes. Put comma-separated addresses in to, cc, or bcc.

Why are cc or replyTo empty in my output record? Those fields reflect what you set on input — if you didn't supply a CC or Reply-To address, the record carries an empty string for that field rather than omitting it.

Is my SMTP password safe? smtpPassword is marked as a secret input, so Apify encrypts it at rest and masks it in the console and logs.

How large can an attachment be? This depends on your SMTP provider's own limits (Gmail allows up to 25 MB per message). Keep total attachment size well under that to avoid provider-side rejection.

What if the SMTP server rejects the connection? The run fails with the server's own error message (authentication failure, connection refused, timeout, etc.) so you can correct the host, port, or credentials.

Can I use port 465 instead of 587? Yes. Set smtpPort to 465 and keep useTls enabled; the actor connects over direct SSL for that port instead of STARTTLS.

Can I choose a different From address or display name? No. The message is sent from the smtpUser address exactly as entered. Use replyTo if replies should go somewhere else.

Does this actor store or forward my emails anywhere? No. Each run only sends the single message you configure through your own SMTP server; nothing is retained beyond the delivery confirmation record.

Python quickstart

Use a schema-derived input and the Python standard library to start a run. An Apify account and token are required for execution.
