Hey Mailbox Providers,
I am a Deliverability Specialist reaching out on behalf of Mailkit about
a client of ours that needs to send out a larger than usual
transactional campaign detailing an important change in the account
entity. Below are more details, but I wanted to apologize for the short
notice. I am reaching out in mailops in an attempt to facilitate
smoother deliverability of these emails.
Subject line: Notification of Change of Website Operator
From address: [email protected]
IP ranges used: 185.136.200.0/22

Again, my apologies for not being able to give more notice. If there is
any more information I can provide, just let me know and I will be happy
to share it. We appreciate any assistance you can provide, and thank you
in advance.
