Hi @matteo,

These bounce messages indicate that there is an issue with the recipients' email server and they cannot receive your emails:

Hard BouncedWe couldn't reach this recipient's email server (MX record)error dialing remote address: dial tcp 146.xxx.xxx:25: i/o timeout

Hard BouncedThe recipient's email server is unable to deliver email due to DNS issues on their endUnable to resolve MX record for domain_name.lt: servfail

These addresses should remain bounced unless you have had correspondence with these contacts outside of HubSpot to confirm that their email addresses are valid.

The rest of the bounce messages indicate that the recipients' email servers rejected your email due to IP reputation. If you send me a private message with the affected email addresses and your HubID I can unbounce the affected addresses and chase down the IP reputation issue.
