SMS
SMS (Short Message Service) is the text messaging service component that enables for text messages to be sent between mobile devices, as well as with services like Heymarket.
Because the service leverages standard protocols, there are some important limitations and considerations that need to be accounted for when using SMS.
While SMS messages can be joined together, messages longer than 160 characters are split by carriers prior to them being sent.
SMS Segments within Heymarket
This has some implications on how many SMS segments you should consider buying when choosing your Heymarket plan. While it may seem that you're sending out an individual message, the number of segments are calculated using the below table:
| Segments | Characters |
| 1 | 0 - 160 |
| 2 | 161 - 306 |
| 3 | 307 - 460 |
| 4 | 461 - 612 |
| 5 | 613 – 765 |
| 6 | 766 - 918 |
| 7 | 919 – 1,071 |
| 8 | 1,072 – 1,224 |
| 9 | 1,225 – 1,377 |
| 10 | 1,378 – 1,530 |
Heymarket will warn you prior to send messages that are greater than 1 segment, so you can be aware of how this will impact your overall message count.
As can be seen in the screenshots below, Heymarket will display the number of segments a message will use next to the Send Now button and provide a warning to ensure you are aware that while an individual message is being sent, several segments will be utilized:
MMS
Similar to SMS, MMS (Multimedia Messaging Service) is the standard protocol that is used to send messages that contain multimedia (images, PDF's, videos, etc.).

If you attempt to upload a multimedia filed larger than 100MB, the upload will be blocked by Heymarket and you will be displayed the following error message:
