AFFECTSRootCause

you probably don’t own this domain — using the email in the example “onboarding@resend.dev”. Tension: you can only send emails from domains you own?

AFFECTSRootCause

It was just a resend version problem — const resend = new Resend(process.env.RESEND_API_KEY); // this doesnt at all. Tension: this works only in dev. Outcome: i just updated it the last one and now it works fine !

AFFECTSRootCause

I was passing in the Data URI as well with the encoding of the file — pass the buffer or the base64 encoded string for the file that you want to attach. Tension: the issue was that I was passing in the Data URI as well with the encoding of the file which broke it. Outcome: doesn't contain this value: `data:@file/png;base64,`.

AFFECTSRootCause

Their api allows you to send up to 50 emails by passing an array of strings into 'to' — send an email with different variables to two different users. Tension: this is not ideal as it means both parties can see each others email.

REQUIRESSolution

Try changing the “from” part — using the email in the example “onboarding@resend.dev”. Tension: you probably don’t own this domain. Outcome: a domain you own and verified via the domains settings here: https://resend.com/domains.

REQUIRESSolution

the issue was that I was passing in the Data URI as well with the encoding of the file. Outcome: make sure that the string of the file that you're sending doesn't contain this value: `data:@file/png;base64,`.

REQUIRESSolution

Use `.batch` from Resend instead of `.emails` — Better way to send more than one email. Tension: instead of `.emails` by utilizing their Batch Emails API. Outcome: Try with these updates to your code.
