Experience with ZeroBounce

[Amanda_Scigaj2]

Part of our BI team is interested in implementing ZeroBounce, which leverages a webhook in Marketo. Typically I'm cagey of using these on large volume campaigns; has anyone had experience with the tool and the integration?

What's "large volume", though?

Even if a webhook service runs at wire speed, due to speed-of-light limitations, you can't call a webhook more than 100,000 times per day, *every single day*, without falling behind. For 50K calls/day or less, you have nothing to worry about.

An initial email validation run typically shouldn't be done via webhook -- ongoing triggered validation, though, certainly can and should.

Its safe to say that we may hit that ceiling from time to time; especially with the project that the team is suggesting. Thanks!
