> The problem I’m seeing with doing this on Zapier is that it could get quite expensive processing User Event webhooks for events that you are not interested in.

A free alternative for listening to the webhooks might be a cloud function. I think you can get 2 million free function executions per month on Firebase. Or 125,000/month [on Netlify](https://www.netlify.com/products/functions/) (uses AWS Lambda).

For the emails, ~~if you already use Mailchimp, then I think the Mandrill add-on might still offer 20,000 free transactional emails per month~~ Mailgun isn’t free any more, but probably wouldn’t be too expensive. Amazon SES would be even cheaper.

**Edit:** Mandrill isn’t free at all, so Mailgun or SES might be the cheapest options. It looks like Mailgun currently is $0.80 per 1,000 emails and SES is $0.10 per 1,000 emails.
