Retry Cloud Functions for Firebase until it succeeds

I'd like to create a cloud function which sends an e-mail based on a change in my database. I use postmark, but that's not relevant for this function. I looked at the firebase-examples.

My question is: What if the mail service returns an error or if the mail service is temporary down? I don't see any form of error handling in the examples.

My 'solution' would be to try again in 5 minutes for example. Is that possible and advisable in cloud functions?

If you throw an exception when sending the email fails, it should retry the function up to 7 days.

Open detailed usage states for your function in the firebase console

Edit the function

Click the link to configure retry

Enable "Retry on failure"

I haven't tried it myself yet for your use case, but it works for my storage triggered function when it fails.
