Message Delivery ← Knowledge Base Why did my message get cut off on an answering machine/voicemail? Are there limits to how many people I can send messages to at once? Can I schedule messages to go out later? Can I send a message when not near a PC? Can I set up the number of retries for each phone call? Does it cost my contacts to receive messages from me? How fast is AlertFirst message delivery? What communication channels does AlertFirst support? What happens when a number is busy or there is no answer? Will AlertFirst leave a message on an answering machine or voicemail? Is there a way for the recipient of a AlertFirst phone call to repeat the pre-recorded message? Is there a way to terminate a phone call/email/text alert that has been activated?
