Automate Birthday/Anniversary congratulatory emails?

Dear Team,

For our contacts in CRM, we need: "An automatic email sent to the contact liest member, triggered by their respective date Of Birth, congratulating them on their Birthday; although we will design and save the templete befor hand, and that the mail merge facility ca be used as is done is bulk emailing. This will be the recurring email sent annually on their Birthdays /marriage anniversaries..."

CRM means Customer Relationship Management, and automatic set up as described above will enable to strike a cord with our contacts and add to the good will and connect with them better.

Not only will this put a better impression on to our clients and vendors, but also save a lot of otherwise manual time.

>>> Looking forward to the earliest resolution of the same.'

Regards
Rajat Dhar
