Spotler SendPro (Flowmailer) SPF Setup

SPF (Sender Policy Framework) is an email authentication protocol that prevents unauthorized senders from sending emails on behalf of your domain. By validating the sending servers, SPF helps protect against spoofing and phishing.

This guide explains how to configure SPF for Spotler SendPro (formerly Flowmailer), a powerful email delivery platform designed for secure and authenticated email communication.

Spotler Sendpro (Flowmailer) SPF Requirements

Note: If you’re already using Sendmarc for SPF management, simply copy ‘include:spf.flowmailer.net’ and follow the steps here.

To authorize Spotler Sendpro to send emails on your domain’s behalf:

  1. Log in to your domain’s DNS dashboard.
  2. Go to the page where you can update the DNS settings on that domain.
  3. Check if a TXT record starting with v=spf1 already exists.
    • If it exists, modify the existing record to include Spotler Sendpro (details in the table below).
    • If not, create a new TXT record.

Example of an updated SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:another.net include:spf.flowmailer.net ~all

Example of a new SPF record:

HostTypeValue
@ or blankTXTv=spf1 include:spf.flowmailer.net ~all
  1. Save your changes in the DNS control panel.

Allow up to 48 hours for DNS propagation, depending on your DNS host.
