Hey @Jon - thanks for your comment.
It seems there are a number of possible third party apps…
- CloudMailIn - https://www.cloudmailin.com
- MailParser - https://mailparser.io
- MailSlurp - https://www.mailslurp.com
- Parseur - https://parseur.com
Monthly subscriptions are from USD25 per month.
(Webhook site is the best value at USD16).
Though they are typically useful for more complicated use cases where mail scaping is required.
With a little trial and error and help from the https://webhook.site support team, I have made this work (in a manner of speaking).
And perhaps somewhere down the road HookDeck (https://hookdeck.com) will get the ability to consume emails too - that is my favourite webhook platform.
