Text Only Messages (SMS)
A single text broadcast message costs 1 credit per recipient. Because every message is sent in segments of 160 characters, any message above that will cost an additional credit and again if the message goes above an additional 160 characters.
Image Messages (MMS)
A single image broadcast message costs 2 credits per recipient. Image messages increase your character count from 160 to 1600.
For example, if you have a campaign where you send a broadcast message to 25 individuals, it would cost 25 credits. If your message is above 160 characters, it will cost 50 credits and if it’s above 320 characters, it will cost 75 credits. If your broadcast message contains an image, it will cost 50 credits.
