To ensure SMS messages are successfully delivered and remain compliant with local carrier and vendor requirements, please follow the guidelines below:
Avoid Mentioning Brands or Company Names
Do not include brand or company names in your SMS content — especially international brands.
If an international brand is detected in the message body, the vendor will classify the number as international, which blocks message delivery.
Short, Clear Messages Win
Keep messages short and clear — the shorter the text, the lower the risk of triggering concatenation. One complete message uses 160 characters.
Avoid sending too many messages in short bursts to the same user to prevent being flagged as spam by local carriers.
Avoid long messages that result in concatenation — some operators allow only up to 3 message parts for a long SMS.
Avoid Emojis and URLs/Links
Do not include emojis or non-standard characters. Emojis use Unicode (16 bits per character), which reduces the total character limit (≈70 per SMS) and increases message segmentation, negatively impacting deliverability and open rates.
Do not include Links or URLs unless they are whitelisted by the messaging carrier to avoid link-based blocking.
Use Basic Characters and avoid using Special Symbols/Characters
Use the following characters to maximize the character limit (≈approximately 160 per SMS) and ensure compatibility and deliverability across networks. Avoid using special characters outside of this list.
Basic Characters (1 character each)
Uppercase letters: A–Z
Lowercase letters: a–z
Digits: 0–9
Punctuation & symbols: These take two character slots
! " # ¤ % & ' ( ) * + , - . /
: ; < = > ? ¡
SP (space), LF (line feed) and CR (carriage return)
