Frequently Asked Questions in Charleston, ME
Everything you need to know about specs, turnarounds, and commercial press quality:
How can I track phone calls and leads from my Charleston postcard mailing?
We recommend placing a dedicated local call tracking number on the mailer, along with a custom QR code that directs smartphone recipients to a dedicated campaign landing page with an exclusive offer.
Do I need to buy a mailing list to send postcards in Charleston?
No! That is the primary advantage of Every Door Direct Mail. You do not purchase names or addresses. Instead, you select postal routes in Penobscot, and the postal carrier delivers your postcard to every single address along that route.
What paper stock do you use for postcards mailed in Charleston?
We print on heavy 16pt commercial cardstock (or 14pt upon request) with your choice of high-gloss UV coating for vibrant color protection or silk matte finish for an elegant glare-free look.
