What does the MSG-058 Error mean?
The MSG-058 error indicates that you are attempting to message from a US or Canadian toll-free phone number which has exceeded the daily limits on message throughput.
United States and Canadian carriers now require businesses to verify their account when sending from toll-free phone numbers at higher quantities.
What is Toll-Free Verification?
The toll-free verification process is free of charge. It pre-qualifies messaging traffic as 'verified' with our downstream peers, which helps to increase message deliverability on the toll-free number.
Verification is not whitelisting, so approval doesn’t guarantee that you won’t experience any blocking. However, as long as the sent messages align with what's stated on the approved verification application, we can work with our peers more swiftly and ask for a block to be removed.
What does it cost?
The toll-free verification process is free of charge.
What action do I need to take?
