What does Blocked mean?

[Amber_L]

Hello @JenniferH76,

That's a great question! The Blocked bounce status means  the ISP has decided not to deliver it, probably because it thought the email was spam. The ISP might be concerned about something in the email, or it rejects email from large senders (like Constant Contact). Here's a guide on the other bounce statuses as well as how to manage them. 

If you have any additional questions, please let us know.

Are these permanently blocked, temporarily, or does it fluctuate as CC negotiates agreements with ISP providers?

Hi @MarieG6 ,

Great question! We have an ISP relations team that works with providers and help resolve any issues that might be contributing to an ISP blocking all Constant Contact mail. ISP's can also block an email based on the content of the message, so you may see some blocks for one email campaign and not another.

We have a contact whose account was just blocked - although they have been receiving our emails weekly for several years. And his wife's account - through the same ISP - was not blocked?

Hello @GuillermoO ,

It's possible that the particular contact's security setup, or how they've taught their email program's algorithm to treat certain email elements (whether consciously or otherwise) has affected your ability to deliver to them. Email programs' algorithms - especially in regards to spam filtering, bouncing, and warning messages - can change depending on a myriad of circumstances.

Your account lacks email self-authentication despite having its own unique domain, which can lead to delivery issues - including your emails being blocked from receiving. I'd recommend setting up self-authentication for your account, and to contact our Delivery team if you need further insight or guidance in either of these regards.
