Email Verifier Questions
Because it helps with email deliverability, protects your domain reputation, helps your emails get into the inbox, and with mailfloss, also fixes typos that would have otherwise been lost.
Have you ever done email verification before? It sucks. mailfloss takes the suck out of it by completely automating the process. It's set and forget.
We are really accurate thanks to our deep clean engine. We don't post accuracy percentages because we don't believe accuracy percentages are...well accurate. They are a marketing ploy that our competitors use without the data to back it up. We put our money where our mouths are. If you aren't satisfied with our results simply ask for your money back within 30 days and we'll oblige.
We have in-app tooltips that guide you as well as help documentation and videos. Look for labels in the app that say "recommended". And if that isn't enough you can simply contact us and we'd be happy to offer suggestions.
Absolutely not. That would be very bad, break some laws, and annoy your subscribers. We use a number of other methods to determine if an email is valid.

We keep your data for 30 days so you can export your results. When we import results from your ESP we only take the email address and discard all other data. The same goes for any files uploaded to us - only the email address column data is kept and the rest is discarded.
Our specialty is definitely our deep email service provider integrations, which do all of the hard work for you. Otherwise, you can copy & paste or upload a csv file to us.
Yes, we are happy to offer a money-back guarantee if you aren't satisfied with your results. We call it the love us satisfaction guarantee. If in 30 days you are not satisfied with the results simply let us know and we'll refund your money.
