Overview

mailfloss is an email validation tool that automatically removes hard bounces, fakes, and misspelled emails from your Sendlane Lists.

Before getting started

  • Create a mailfloss account

Integrate mailfloss and Sendlane

  1. Log into mailfloss

  3. Click Add Integration

  4. Search for and select Sendlane

  5. Enter your API, hash, and Sendlane domain

  6. Click Connect

  7. Select a frequency

    1. Safe (recommended): this means that mailfloss will only remove the ones they are absolutely certain that are not valid.

    2. Medium: this option will allow mailfloss to search for nonexistent and disposable email addresses, in addition to the above option

    3. Aggressive (not recommended): basically anything that looks remotely bad will be removed. This option is not recommended for most users

    4. Custom floss: if none of the above suit your needs and comes with a couple of options for you to choose from, see below
