Hi all, We will begin warming up the following new Class C netblock starting within the next 14 to 28 days:
204.14.47.0/26 (Range: 204.14.47.1 – 204.14.47.62) These are likely marked as "unused IPs" This block will initially serve as a 1:1 replacement for traffic currently sent from: 38.150.92.0/26 Mail volume will ramp gradually as we transition approved traffic over. All sends will be strictly permission-based and transactional email , authenticated with SPF, DKIM, and DMARC. Abuse, bounce processing, and feedback loops are monitored closely. Important: If you’ve had any issues with senders on 38.150.92.0/26, please reach out off-list. We will exclude those clients from the migration. You can reliably identify our traffic by checking the Domain: header. After the initial warmup is complete, we plan to expand usage to the full 204.14.47.0/24 as volume demands. Additional segments of the range will be brought online gradually, with appropriate warmup and monitoring. WHOIS / ASN Info: • ARIN Org – SENDL • ASN 40019 – ARIN Thanks in advance for your time and coordination. Best regards, Damon Sauer Sendlane Inc.
