Having just tuned up our waterfall testing lots of providers, two things i can recommend checking out
- 1.
Put FullEnrich as your last email provider (if using api keys before otherwise try playing with order) . Only 2 credits which is cheaper than going direct. Checks around 15 providers in its own waterfall.
- 2.
Try Bounce Ban as a verifier. Solid with catch alls. You need to go direct as not available with clay credits, there is an http api template for this in clay. Its really good at catch all verification and standard.
With sending to catch alls , be cautious to do this once your domains are healthy, aged and even run on a seperate campaign so you can turn off quick if bounces spike. These are the ones not marked as safe to send, but if youre contacting larger orgs, theyre mostly going to be catch all.
Additionally, if you use zerobounce in addition to leadmagic, you can get the MX provider for most of your emails. Separate microsoft from everything else in a different sequence and use very short email copy. Your emails will be far less likely to land in spam.
Hope that helps.
