Overview

Text messages in Endear have character limits to ensure high deliverability and avoid triggering SPAM alerts. The length of your message depends on the type of characters you use.

Character Limits

Endear supports two types of text message character limits:

Standard messages (typically 600 characters, but may vary by brand)

  • Messages using standard English letters, numbers, and basic punctuation

  • Standard keyboard symbols like %, &, $, !, ?, and @ do not reduce your character limit

Messages with special characters (typically 240-260 characters)

  • Any message containing emojis (😊, 🎉, ❤️)

  • Letters with accents or diacritical marks (ö, é, ñ, ü)

  • Non-Latin scripts and characters (including Spanish, Chinese, Arabic, Hebrew, and other languages that use extended character sets)

  • Special symbols (©, ™, ✓, •)

Why Are There Different Limits?

These limits are industry-wide SMS standards, not Endear limitations. SMS carriers use different encoding methods. Once you include even one special character, emoji, or non-Latin character anywhere in your message, the entire message must use a different encoding, which reduces your available character count.

How to Maximize Your Character Count

If you need to write a longer message:

  1. Remove any emojis or special symbols

  2. Replace accented letters with their standard equivalents (é becomes e)

  3. Use standard English letters and basic punctuation only

Important Notes

  • If you attempt to send a message that exceeds the limit, you'll see an error message

  • Note: Merge fields that expand when sent will not prevent messages from being sent, even if they push the final message over the limit

Including Images in Text Messages

Images do not count toward your character limit. However:

  • Images must be smaller than 800 pixels wide to be sent

  • Each product or Story counts as one image

  • Single images are sent as MMS (visible in the message thread when possible)

  • Multiple images are automatically delivered as links

  • Due to global carrier limitations, images may not always render in the message thread, but will always be available through a link

  • Including images does not increase the cost of sending texts
