How can I upload, enter, or import emails to mailfloss?

You can upload emails via a correctly formatted .csv file, or you can copy and paste your emails into a text box within the mailfloss app. If your .csv file is larger than 8 MB we ask that you get in touch with us so we can help start the session for you.

Importing your emails with one of our supported email service provider integrations is our preference. We work hard on them to ensure they are the best and most convenient way for you to import your emails to us. Please follow the specific instructions for each ESP. Once connected, you can simply click the "Start scan & floss" button from your connected integration page to begin flossing your entire list (this button was previously labeled "Import & floss everything").
