Character limits and details about sending text messages.
In order to preserve high deliverability of text messages and avoid setting off SPAM alerts, Endear limits the length of text messages to 600 characters so long as you don't use any special characters; the limit is 260 characters if you're using special characters.
Special characters include emojis, letters with accents such as ö, or symbols, such as © or ✓. If you are using text that is not readily available as a standard keyboard key, it is likely a special character. Punctuation marks and symbols on your keyboard such as % or & are not considered special characters.
For reference, here is how messages of these lengths appear to your recipients:
Images in Text Message
If you send only one image, we will attempt to deliver it as an MMS (the image will be visible in the chat thread). Due to global carrier limitations, we cannot promise that images will be rendered in your message, but the image will always be available through a link. If you include more than one image in your text, we will automatically deliver all your images as links instead. Products and lookbooks in Endear each count as one image.
Endear's message compose field offers a character counter to help you efficiently write your message with these limitations in mind. If you try to send a message that's too long, you'll also receive an error message indicating that the length of your message has prevented it from being sent.
