We appreciate your continued participation in the Community! While the Tweet us option for support does have a character limit (this is a Twitter restriction), customers do have the option to direct message us for support as well and there is a 10k character limit there. We choose to provide our customers with as many options to contact us for support so that they can contact us on their terms. I do also want to mention that we staff our Community and Social channels from 8am-8pm ET Monday through Friday, 10am-8pm ET on Saturdays, and 10am-6pm ET on Sundays.
Regarding your concern that only half your customers are opening your emails because of the "This May be Spam" message from google, are you able to provide a screenshot of the message? Once we can see the exact message your seeing, we'll be able to assist further.
