Editors' Review by the Email Marketing Software Review Team

mailfloss is an advanced email verification platform where email marketers, e-commerce shops and businesses of all sizes can automate email validation. You don’t need to use APIs or spreadsheets with this solution. Additionally, it’s a cloud-based and fully automated platform where users can enjoy several benefits and a multitude of features. This includes automated daily unsubscribes, tagging options, detailed reporting, disposable email detection, bulk email verification and spam detection.

What makes mailfloss different than other email verification platforms is the fact that it aims to automate and simplify the processes behind verifying your emails. If done manually, this becomes time-consuming and error-prone. To avoid having to deal with this drawn-out process, businesses and companies often make use of mailfloss to maximize email deliverability and ROI.

mailfloss currently integrates with a wide range of email service providers including MailChimp, Ontraport, HubSpot, Campaign Monitor, AWeber, Constant Contact, Infusionsoft, ActiveCampaign, CovertKit, Drip, Klaviyo, Sendlane, Sendinblue, MailerLite, and Moosend.

Email verification is a crucial process in improving the security of email accounts. It helps establish communication between a business and its customers. Without it, it’s difficult to engage your clients and build a strong relationship with them. Additionally, this helps in identifying if the email entered is authentic. Many people might’ve accidentally entered an old email or misspelled their address. To avoid this, the process of email verifying becomes crucial. This also helps to protect the reputation of your email addresses as bounces are made much easier to avoid.

All that’s required to get started with mailfloss is the following steps:

  • Connecting your email service provider with mailfloss
  • Letting mailfloss automatically clean your emails
  • Customizing which categories need to be automated

mailfloss Features

Bulk email verification

mailfoss can easily manage the verification of emails regardless of batch size. Users can either simply connect mailfloss to their email service provider and let it run automatically or avail of prepaid credits for one-time bulk verifications. Additionally, since mailfloss allows for individual credit purchases covering up to 2.5 million emails there is effectively no limit as far as the majority of users will be concerned.

Overall, this significantly reduces the amount of time it would usually take to finish these verification tasks if they were done manually.

Disposable email detection

This second feature allows you to detect disposable email addresses, which aren’t useful for your business. These are commonly used by people who don’t want to provide their real email addresses. By detecting this early on you can prevent, for example, people from abusing the free plans your business offers⁠—which otherwise could affect the conversion ratio of trial customers to paying ones.

Spam trap detection

This works as a fraud management tool that helps you identify and block spammers from your system. Often, you’ll find your emails being marked as spam, which harms your business as you won’t be able to reach your customers through their main inboxes. Without spam trap detection, your bounce rate will increase and your IP addresses could be added to a blacklist database.

Role-based detection

mailfloss allows you to identify role-based email addresses. By identifying them, you can avoid high bounce rates, spam traps and high spam complaints. As such, mailfloss makes it easier to reach email addresses associated with real people instead of companies or departments.

Syntax validation

Syntax validation utilizes a real-time API where your service can scan all email addresses in your list. It helps to identify faulty email addresses and hold them for closer inspection. This ensures you’ll be dealing with authentic and correct emails instead of erroneous ones.
