Integrating your own sender email


  1. Go to Fileflare > Settings
  2. Go to Email
  3. Scroll down until you see the sender options and choose SMTP


What is SMTP?


The Simple Mail Transfer Protocol (SMTP) is a technical standard for transmitting email over a network. Like other networking protocols, SMTP allows computers and servers to exchange data regardless of their underlying hardware or software. SMTP is a mail delivery protocol, not a mail retrieval protocol. It simply allows apps to connect and send emails using your mail account.


Types of SMTP you can connect


Fileflare allows you to connect your own email address, allowing Fileflare to send download emails using your email. There are a few methods for doing this:


  • Option 1 - SMTP direct to email account - Connecting your email directly to Fileflare using SMTP to allow Fileflare to send emails using your account.
  • Option 2 (recommended) - SMTP providers - Most email apps provide the ability to connect using SMTP. If you have a favourite one to use, check to see if they have SMTP functionality.


  • View email tracking and insights
  • Get the best deliverability; the platforms help you set everything up easily
  • Dedicated IPs to improve email deliverability
  • Use any email address for your domain, even if it's not a real email. E.g. downloads@example.com
  • Works alongside and does not conflict with your existing email system, such as Google Workspace etc.
  • Easier to set up


How to do it



Google Workspace users - Google no longer supports SMTP. Alternatively, you can use the methods below in option 2. These platforms work by verifying your email's domain with the platform using DNS (this does not cause interruption to your current email setup or domain DNS), and then integrating the platform with Fileflare via SMTP details. This method ensures optimal email deliverability. It may sound scary to set up, but it's very easy and better than regular SMTP.


Option 2 - Using an SMTP provider (setup time est. 5-10 minutes)

There are many providers that allow connecting your domain via SMTP. This works alongside any other email setup which does not cause interruption to your mail accounts.
