Dear Mailops Community, I am writing to inform you that Cordial is expanding our outbound sending IPs. We are an ESP sending authenticated commercial email on behalf of multiple brands. We are provisioning an additional /22 from our existing /21 block.
Technical Details: Start Date: February 2, 2026 Current Range: 192.112.152.0/22 New Range: 192.112.156.0/22 (these are within the same contiguous /21 we own) ASN: 401181 Activation Strategy: While the full /22 range will be advertised starting Feb 2, 2026, we will not be utilising all IPs immediately. We will activate IPs within this block as needed. Any newly activated IP will undergo a standard warm-up protocol. All traffic will be fully authenticated with SPF, DKIM and DMARC. If you observe any issues or have questions regarding traffic from this new range, please reach out to our abuse desk at [email protected] -- Steven Lunniss Director of Deliverability, Cordial
