Anyone here have any insight on Instantly vs. Zerobounce for email verification?

I use trykitt with my own api key at the beginning of the waterfall ($1.5/1k verifies), then zerobounce or whatever else you like

yeah, i’ve used both. instantly is okay for a quick pass, but zerobounce is what i rely on to actually keep bounce rates down. i usually run zerobounce first, then send from instantly.
