Send a greeting card Three
Forth, printed on greeting card your name and title, but handwritten in envelopes
If you order a greeting card early enough, you can find businesses that offer greeting card customization services, so that they print your name and title on the greeting card and make your greeting card look more professional.
But in order to make your greeting card does not look like "mass production", you'd better handwritten the envelope. If you are not empty, let your secretary, friend or family help you.
When writing the name of the recipient on the envelope, use the personal title such as "Mr.", "Ms.", "Doctor". Make sure the mailing address is accurate.
