Issue with your BCC email bouncing

Hi! I need help/advice.

The mailboxes we BCC are returning this error, which we translate as “mailbox full”. However, it seems to be more likely a recipient limit: 450-4.2.1 The user you are trying to contact is receiving mail at a rate that 450-4.2.1 prevents additional messages from being delivered. Please resend your 450-4.2.1 message at a later time. If the user is able to receive mail at that 450-4.2.1 time, your message will be delivered.

In the past 30 days, our portal has sent about 24 million messages. We’ve seen about 22 million of the BCCd messages fail with that error.
has anyone experienced something similar and did you have to get a new thirday party archiving system to solve this issue? IF so what third party archiving system did you use?

Hi @CKaufman9,

Considering that volume, I’d recommend reaching out to HubSpot technical support or your account manager directly. There isn’t a mentioned technical limit for the BCC address specifically: https://legal.hubspot.com/hubspot-product-and-services-catalog

Support (in-app, via chat or email) or your account manager should be able to confirm any hard limits and whether these can be increased potentially by upgrading.

Best regards
