While using Heymarket, you may see messages displayed as "Failed". While there are a few different reasons a message may fail to send (feel free to message into Support at (415) 562-0100 to determine the specific failure reason), one common explanation could be the receiving carrier is blocking the delivery of the message because they perceive it to be potential spam. This is known as carrier filtering.
While the carrier filtering specifics are not publicly shared by the receiving mobile carriers (T-Mobile, AT&T, Verizon, etc.), we've been able to identify some specific things that will increase your likelihood of getting filtered. This article will provide several strategies for your review and adoption into business messaging as we recommend these tips to improve messaging deliverability.
- Please provide appropriate "Opt-Out" options to give the end user the power in the conversation. Carriers will look for phrases like "Don't want to get these messages? Reply STOP to opt out." in order to give their subscribers the option to continue.
- If this option is not given, the end users are much more likely to report your number as SPAM which will hurt your number's overall deliverability.
- For improved deliverability, include an opt-out message in all outbound communications, especially if experiencing increased delivery failures.
- Please avoid any line breaks (pressing Shift+Enter on your keyboard to indent) as these have a higher likelihood of getting filtered as potential spam.
- Please avoid any shortened links (bit.ly, tiny.URL, etc.) as these have a higher likelihood of getting filtered as potential spam.
- Please keep your messages as personalized as possible. Receiving carriers will more likely successfully deliver your message if it begins with "Hello {{first_name}}, thanks for reaching out about XXX" (this is just an example, but if your messaging looks like it is requested/desired, it is less likely filtered)
- Please avoid the use of any specific financial language. Messages containing phrases about loans, money "asks," or specific dollar amounts are much more likely to be carrier filtered as spammers will use this language to attempt to receive money. These types of conversations are best carried out over other channels
