## What the story says

Tesco Bank's CRM team sends customer emails through Optimove and SendGrid. After Microsoft began blocking its messages, it worked with Optimove to audit the sending program, reset sender reputation, whitelist sending IPs and suppress non-engaging addresses, and it now runs a recurring blocked-address suppression routine.

Summary written by usedby from the source page, in English. The figures are those of Optimove and Tesco Bank, not ours.

> The fix worked. Tesco Bank's emails returned to the inbox, and customers began receiving them again. Inbox placement recovered, and the sender's reputation that had taken the damage was rebuilt to excellent.

> We have the skill set in-house which, coupled with the expertise we can leverage with Optimove, means we know what we're doing. And while we can't always guarantee we won't hit another problem, if we do, we know what to do.
