Does sogou spend money on writing and texting?

The fees generated by SMS are charged by the network operators and have nothing to do with sogou.

However, if you send MMS, sogou will not charge extra MMS fee. You can add files, videos, audio and pictures to the message, and sogou will generate an encrypted link. The other party will receive the link and access password. The link will be valid within 12 hours, and the file will be invalid after 12 hours.
