Clay has a bunch of native integrations or you can use api keys within the native integrations. You should focus on providers who do both regular and catch all email validation. Can check Enrichley

Enrichley does both regular verification and catch all verification. Native integration within Clay

Every provider within Clay just as a comparison. Worth running some tests! Also worth tracking bounces to ensure they're all hard bounces for invalid emails since those are the ones email verifiers shouldn't have above 2%

You should do some sample testing across vendors within Clay. Main thing to look for is coverage but a few have bounce issues (have tested them all at scale). Can check Enrichley has best coverage and sub 2% bounce rates

If you want cost effectiveness you can use a cheap smtp tool like millionverifier then for any unknown or catch all statuses can run through a tool like enrichley (natively in clay). Had some agencies test against all catch all verification tools in clay and seeing minimum 5-10% more coverage and sub 2% bounce rates.

I almost guarantee your bounces are due to your sense reputation if multiple providers are giving you high bounce rates. If you use SmartLead I'd check out uplifty.io since it'll tell you why you're bouncing

I’d just get a central storage db going. The cheapest and most user friendly one would be something like supabase then just have all your different tables/automations referencing that as your global db.

Unfortunately it’s only integrated with SmartLead at the moment (hopefully adding more integrations soon)

If you use Smartlead you can check out uplifty.io, could be that your mailboxes/domains are burned without you knowing.

Be aware this is the easiest way to get your LinkedIn account restricted. They monitor what chrome extensions are interacting with their platform so just be aware but there are extensions out there for this
