Hi ProductHunt, we've build Uncatcher, a platform that solves one of the most annoying problem in outbound sales and email marketing - catch-all emails (a.k.a. risky/unknown/accept-all). We are able to verify catch-all emails with up to 100% certainty. If we say it's valid - it's actually valid! This allows you to reach prospect that essentially one else can, at the same time avoiding penalties on your domain reputation when your emails bounce off of non-existing mailboxes. Billing is solely based on usage, there are no subscriptions. One successful verification costs 1 credit (successful = we're sure that email is either valid or invalid). If we can't tell email's status, you don't pay anything. You can verify emails one by one or in bulk, either pasting a list of emails or uploading a CSV. A REST API is also available and we have tutorials to integrate with Google Sheets and Clay. You can start with a trial account that has 100 free verifications included. The cheapest credit package starts at just $9 and includes 1,000 credits. Cheers, and happy emailing! P.S. You can get a 50% discount on Pro package that includes 15,000 verifications with LAUNCH50PRO promo code at the checkout!

I can already see an increase in my email engagement since using this. It's an essential for me serious about email marketing.
