FAQ - Massive Messenger


How many characters can I send in an SMS message?

A standard SMS message has a maximum of 160 characters. You can send Longer messages, but be aware that exceeding 160 characters will deliver a ‘second’ message. The recipient will see this as 1 long message when received.

Do you allow non opt-in marketing lists?

No we do not. We are compliant with Telephone Consumer Protection Act (TCPA) and CAN-SPAM regulations.

Do you support Emoji in SMS?

Yes we do! We support emojis for all SMS, but we recommend testing first because not all devices and carriers support emojis ☹️.

Emoji characters take up more character space than a normal character. As a result, once you use an Emoji character, your character limit is reduced to 70 characters instead of 160. This is a network limitation affecting all providers in all countries (not a Massivemessenger thing)

How fast can you send messages?

Generally, messages are delivered within 5 seconds. If you’re sending a large amount (over 100k), we put the messages in a queue and deliver them at a rate of up to 30,000 messages per minute.

Can I insert a URL or hyperlink into an SMS message?

If you use a valid URL in the message body, most devices automatically convert it to a tappable link.
