Yellow Letters Complete was founded in 2006 and has grown into one of the largest hand-addressed envelope companies in the world. They help grow businesses with direct mail marketing by mailing letters in hand addressed envelopes to targeted mailing lists. Yellow Letters Complete employs a team of over 60 individuals and mails out over one million hand addressed envelopes yearly. They offer yellow letters, letterhead letters, letters with a hand-signed wet-ink signature, postcards and targeted mailing lists in an easy to use, turnkey system. By using invitation style envelopes hand addressed by real people, Yellow Letters Complete is able to generate more responses from a targeted mailing list than traditional direct mail marketing methods.
