2020-06-08 Thread Laurent S. via mailop
Hi, Related to the thread of a few days ago "Force double opt in for marketing list companies per email address": Which ESP does 100% (double/confirmed) opt in? I am looking for an ESP that will, in every case, send a confirmation link without ever trusting their clients about the consent

[mailop] hotmail.com SPF forgot IPv6

2023-08-18 Thread Laurent S. via mailop
Aloha hotmail, It seems since you recently changed your SPF and switched from ~all to -all. It would have been great if you didn't remove at the same time your IPv6 ranges from it. It seems the include:spf.protection.outlook.com was removed during the change. You might want to include it
