What does it mean if my text says "Sent" but there's no "Delivered" status?

It means your phone successfully sent the message to your carrier (or messaging service's server), but there's no confirmation that it reached the recipient's device. This could be due to various reasons: the recipient's phone might be off, out of service, have a full inbox, or there might be network issues. It could also mean you have the wrong number.

Why do my WhatsApp messages only have one grey tick?

One grey tick means the message has successfully been sent from your device and reached WhatsApp's servers. It has not yet been delivered to the recipient's phone. This usually indicates a problem with the recipient's internet connection, or that they have WhatsApp closed (and haven't received the background notification).

Are SMS delivery reports accurate?

Generally, no, SMS delivery reports are not completely reliable. They usually only confirm that the message reached the recipient's mobile carrier's network, not necessarily the recipient's device. A phone that is turned off, for example, won't receive the message, even though the carrier did.

Does "Delivered" mean the recipient has read my message?

No. "Delivered" only means the message has reached the recipient's device or messaging service inbox (or mail server, for email). It does not indicate that the recipient has opened or read the message. "Read" receipts (like WhatsApp's blue ticks or iMessage's "Read" status) are separate indicators that show when a message has been read, and these are often optional settings.

How can I improve my SMS deliverability rates?

To improve your SMS deliverability, use a trusted provider like CallMama for reliable delivery. Ensure recipient numbers are correct and avoid spam triggers like certain words and excessive links. For high-volume messaging, consider using short codes for better results. Lastly, comply with regulations to maintain a positive sender reputation.
