    Verify Your Domain

    Before sending, you need to verify ownership of your sending domain and configure DNS records to improve deliverability.

    a

    Add your domain

    In the dashboard, navigate to the Domains page and click Add Domain. Enter the domain you want to send from (e.g. mail.yourdomain.com).
    b

    Add DNS records

    Simply Send will generate the required DNS records (SPF, DKIM, DMARC). Add these to your DNS provider. This typically takes a few minutes to propagate.
    c

    Wait for verification

    Once DNS has propagated, your domain status will update to Verified. You can then use it as a sending domain.

    Set Up Compliance Templates

    Transactional and marketing emails use Compliance Templates for required unsubscribe and company-address content. A report-abuse template can also be included when configured.

    →

    Configure compliance info

    Go to the Templates page and select the Compliance Templates tab. Fill in your physical mailing address and configure your unsubscribe link.
    • Simply Send automatically creates a pre-approved unsubscribe_email_html template when you sign up.
    • Create and get approval for a company_address_html template before sending.
    • If you configure a report-abuse template, add its report_abuse_email_html marker too.
    Include the corresponding markers in your email HTML as {{unsubscribe_email_html}}, {{company_address_html}}, and (when configured) {{report_abuse_email_html}}. Simply Send replaces each marker with its configured template when sending.

    Send Your First Email

    With your domain verified and API key in hand, you're ready to send. Replace the placeholders below with your real values and fire off your first request.

    • your_api_key_here — the Transactional API key you generated
    • your_account_id — your Account ID from the Account page
    • [email protected] — your verified sending domain address

    A successful response returns a 200 OK with a message ID. Check your Email Events page to see the delivery status in real time.
