We want to send emails to our donors of the previous week. This email needs to be customised, as it's an opportunity to tell them what has happen in the week or what's the plan to the week ahead.
I tried to use the thank you letter feature, but I haven't been able to customise much of the email (eg. the subject line) easily for each mailing.
If I do a "normal" mailing from an advanced search on donors, I haven't found an easy way to set the "thank you" date on the contribution, and only filtering on the contribution date isn't robust enough, and I'd like to use that field to know as well when the donor has received the thank you email.
