Here's a great story about how our Yellow Letters fooled the US Postal Service. OMG!


When we first created this product and brought the trays of bulk mail to the post office, the USPS clerk in the Bulk Mail Entry Unit initially denied our mailing.  He said that handwritten letters are not eligible for bulk mail; they must be mailed first class.  Well, we designed these mailers to qualify for the lower bulk mail postage rates so we challenged the postal service clerk to look again.  He opened up a mail piece and was absolutely convinced these letters were all handwritten.  We tried to tell him we manufacture these on digital printers with an incredibly authentic handwritten font that makes them appear like a human wrote the letter.  He still didn't believe us.  So we told him to hold the letter up to the light and see if he could identify the indentation from the person pressing down and writing on the paper.  He couldn't find the indentation and reluctantly agreed that these letters do qualify for bulk mail postage rates!

The secret of the yellow letter is it’s personal appearance. It is a “pattern interrupt” marketing piece that makes you stop when you get your mail. When people receive their mail they quickly sort into an A Pile (good stuff) and B Pile (recycle bin).  The incredible personalization of Yellow Letters virtually guarantee you will be in the A Pile and positioned to have your message read and understood.

Pssst... Want to know another secret?


When we designed our Yellow Letter product, we tried to use every trick in the book. We start by using an actual stamp, not a postal indicia. Then we use a fake cancellation to cancel the stamp and give it a first class look.  Normally bulk stamps just sit out there naked. 1st class stamps are the ones USPS cancels. So we do a fake cancellation to make it look like a first class letter. This is perfectly legal with USPS rules.

Your Time is Too Valuable to Do this Yourself


As you can imagine, the process of writing, folding, stuffing, and stamping these letters is a time consuming but crucial part of your campaign. And Trigger Response can get it done faster and cheaper than anyway you could do yourself.


Our Yellow Letter service is no frills with no upselling or mandatory big minimum purchases. Buy only what you need, when you need it. (as long as you meet 200 piece minimum quantity for bulk mail as determined by USPS). But if you are willing to commit to a larger quantity, then we will reward you with even cheaper prices.


You simply order your letters, upload your mailing list, and we’ll take care of the rest.

The "handwritten" Yellow Letter is:


1. a letter with an authentic, almost real handwritten font that has even fooled the post office.
2. a personalized letter customized with content for that specific recipient powered by variable data digital printing
3. printed on old school yellow ruled paper or plain white paper.


And it is enclosed in an amazing 6″x9.5″ envelope that:
1. looks like a birthday card from grandma. Astrobright 6″x9″ envelope with same authentic handwritten font.
2. has a real stamp affixed to envelope.
3. has a ‘fake cancellation’ over the stamp so you get a first class look while paying bulk rate postage. This is secret but perfectly legal per USPS rules.


Your customers, prospects, constituents and donors can’t resist reading this letter!
