Totally feeling the pain here...From what I’ve seen and heard, it could be anything from overly strict recipient filters to something going on with Smartlead’s sending IPs. The content of the emails might also be triggering something, even if everything else checks out. Just wondering if anyone else is seeing the same thing or figured out what’s really behind it?

Hey i have the same issue with "Sender Bounced" being extremely high. I have a list of 10k people and already sent to 2.5k of them with some inboxes managed by a provider in the US. Then i tried to send two campaigns with the rest of the 10k leads with accounts created by SmartSenders (SmartLead) and both times the campaigns had huge sender bounced rate. SmartLead make it sound that its all good on their side and assuring me it might be the list, the recipients inboxes, etc. but i highly doubt that the first 2.5k leads had no issues and then the rest do. Anyone with a similar problem and did you manage to solve it? I am considering moving my inboxes away from them because of that.

Did you update the records and reconnect the inboxes?

Totally missed your message Stephen K. Since the mailboxes and records are all managed my Smartlead i was going back and forth with them. Eventually they fixed most of them and I am sending the rest out successfully at the moment. I still have issues with 10 mailboxes
