Direct-to-Voicemail - Voicemail Broadcast Issues
Direct-to-Voicemail is a tricky beast! Because each carrier has its own methods, you cannot rely on 100% delivery. (Our providers are reporting an 86-87% delivery rate.) You should treat this type of message as a 'bonus' message, and not use it for mission critical messaging.
Some known issues include the following:
- Your cell number was ported from one cell provider to your current provider. If your number was ported, many providers will not relay messages to your current provider.
- You might not have had a strong signal. Just as with a call, if you don't have a signal, you may not get the message.
- Your provider may have had issues at the time the message was sent. Technical issues on your provider's end are common, oftentimes temporary, and impossible to predict.
- You may have requested all SMS messages to be stopped. You may have responded to another text campaign using the word STOP -- this is a universal opt-out word, and it may prevent you from receiving messages, even those you want, from other campaigns.
- Your opt-in via SMS is not confirmed. This is VERY common -- If you look at the subscriber record in your campaign, and a red circle appears in the SMS field, it indicates that the SMS opt-in is not confirmed. It might be unconfirmed because the subscriber opted in via a website. If you had opted-in via your cell phone, you would have immediately received your voice message. A direct request to join a campaign via a cell phone is considered a confirmed SMS opt-in. Adding a cell number via a webform is not. Opting in via webform would result in an immediate SMS message asking the subscriber to respond 'yes' to confirm their opt-in. If ignored, the status will remain unconfirmed.
- With Verizon, a long delay is added to the start of a message. This causes some messages to not be delivered. We do not have a clear handle on this from Verizon, but our own testing shows that the voicemail will cut the message off because it 'listens' to the message and hears nothing, and so assumes the call was disconnected.
- Some carriers will add a short delay to the start of the message, but if the subscriber continues to listen, the message is delivered in its entirety.
- If a message starts out at a low volume, or if it includes a long delay, the message may not be delivered because it seems to be considered as the call was disconnected. (Your message, by the way, was recorded fine and plays back at a good volume and without a delay.)
- Some carriers do not accept direct-to-voicemail messages.
- Some carriers (T-mobile, for example) have absolutely no problems delivering most messages.
