Resend Rate Limits

Hi guys, We're currently experiencing a bit of an issue when bulk triggering workflows alongside Resend as our main email provider. The message coming from Resend:

{
    "name": "rate_limit_exceeded",
    "message": "Too many requests. You can only make 2 requests per second. See rate limit response headers for more information. Or contact support to increase rate limit.",
    "statusCode": 429
}

{
    "name": "rate_limit_exceeded",
    "message": "Too many requests. You can only make 2 requests per second. See rate limit response headers for more information. Or contact support to increase rate limit.",
    "statusCode": 429
}

Is this something that's avoidable using Novu? How can we ensure we don't hit these limits? For some extra context here, we bulk send to everyone in a "workspace" a-la-Slack using a novu topic, so it's not something I can see us fixing ourselves. Appreciate that this is a pretty vague question, but as we're not hitting resend directly ourselves, I'm unsure on how we can avoid this.

Extra info here: We'll do max maybe 5 people to contact in one go so far, and they're few and far between, requests like this come in every 1 - 2 hours or so right now. A bit of a side note, I can see the requests failing in Novu Cloud

However, opening it gives me no data - even after a login-logout, even after switching environments and back
