Handwriting & Fonts - FAQs
Is the handwriting real or digital?
Digital. thanks.io uses a proprietary handwriting engine that renders handwritten-style script. It is a fully automated digital printing process.
What handwriting fonts are available?
A library of handwriting-style fonts ranging from casual to neat and professional. Browse and preview in the Message Template editor. Standard (non-handwriting) fonts are also available and labeled as Normal Print.
Do character limits vary by handwriting style?
Yes. Because each font has different glyph sizes, the number of characters that fit on a mailer depends on both the style and the specific letters used. A message with many narrow letters (like "i") will fit more text than one with many wide letters (like "m" or "a"). Check the character count indicator in the Message Template editor.
What ink colors are available?
The default ink color is black. You can change it in your account settings. Available colors are:
- Blue
- Black
- Green
- Purple
- Red
- White (useful for dark-background designs)
Does my handwriting style apply to the envelope too?
No. The handwriting style on the envelope is fixed and cannot be changed. Handwritten envelopes are available on notecards, gift cards, and windowless letters only.
If you want the text inside your mailer to look similar to the envelope, use the AI Font Analytic Atom in blue - it is the closest match to the envelope handwriting style.
What are AI Fonts?
AI Fonts apply randomized character placement and spacing so each mail piece in a batch looks subtly different - no two pieces are pixel-identical.
What is Realism Mode?
Realism Mode adds subtle imperfections (slight crossouts, minor irregularities) to make the rendering look even more like a naturally handwritten note.
Can I use custom fonts?
No - thanks.io uses its own font library. Browse available fonts in the Message Template editor to find the closest match to your preferred style.
Can the font on the address portion of a postcard or envelope be changed?
No - the address fonts are fixed and cannot be customized.
- Postcards use a typed font that meets USPS guidelines for postal permits. This is required for the mail to process correctly through their automated systems.
- Envelopes use a handwritten-style font chosen for both legibility and a welcoming look. The blue ink adds a personal touch that has been shown to increase open rates.
These choices are intentional - they balance postal compliance, readability, and aesthetics to make a strong first impression.
Is the recipient address handwritten?
It depends on the mailer type:
- Windowless letters, notecards, and gift cards - yes, the recipient and return address are written in a handwriting-style font.
- Postcards and windowed letters - no, the address uses a typed font for USPS processing compatibility.
