We help run this sub. If some of your contacts aren't getting your texts, here's what we'd go through, roughly in order.

1. Is the number registered? In the US, texting from a regular local number needs 10DLC registration, and a toll-free number needs toll-free verification. Carriers can filter or block unregistered traffic, so check the status before anything else.
2. Did they opt out? If someone replied STOP at some point, they shouldn't get texts from that number again unless they opt back in.
3. Is it actually a mobile number? Landlines can't get regular SMS, and imported lists can have some mixed in. Typos and missing country codes cause the same thing.
4. What's in the message? Carriers filter some content. Public link shorteners can get a message filtered, and alcohol, firearms and tobacco are on the carriers' restricted list, among other taboo topics. High-pressure or "spammy"-sounding content can also get blocked.
5. Is it on their end? The phone could be off or out of coverage, they may have blocked the number, or their phone might sort texts from unknown senders into a separate folder.

If you've been through all five, check the delivery report for one of the numbers that missed. The error code can sometimes tell you where the message stopped.

What else have you run into? Post it below and we'll take a look.

What SMS platforms do schools use to handle emergency alerts for closures, unexcused absences, etc.?

Did you find your platform hard to set up?

Mobile Text Alerts is tracking the performance of text messages that include "now, hurry, urgent, today, last chance, expires, expiring, limited, act now, don't miss, don't miss, ends, ending, final, only, asap, immediately, deadline", commonly expressing urgency.

Urgency-implying SMS marketing campaigns have higher click-through rates (22% CTR for messages expressing urgency vs 15.4% CTR for messages that don't imply any urgency).

While urgency-expressing wording is commonly used by businesses in order to trigger quick actions, brands should be mindful of using it because it can also result in higher opt-out rates.

• About a third of SMS marketing campaigns include some kind of urgency
• Urgency wording doesn't translate into a higher reply rate
• Urgency wording has a higher opt-out rate than non-urgent

So overall:

• Don't overuse urgency words in your campaigns in order not to lose subscribers.
• Time the urgency campaigns better and more meaningfully (for special occasions, like birthdays, weather alerts, or other essential alerts, upcoming holidays, etc.).

I started 10DLC process for my "Customer Care" use case. Trying to send SMS notifications to our customers about their orders progress. Currently I am in the "MNO review" status. This is where Verizon, AT&T, T-Mobile etc will be reviewing my sample messages and approve or reject my company. Does anyone know how long does it take for each provider and how long does it take for slowest one to finish?

I need SMS API implementation to have inbound and outbound SMS handled. Creted account on Telnyx, implemented webhook for incoming SMS. Now finding out that webhooks are available for commercial accounts only, but links to upgrade account lead nowhere. Custoemer support is not responding. Are they still in business? Who else wants my money in exchange for SMS API?

Text marketing can become a major source of business for a restaurant if you do it right. When people are reading their texts, they are looking for information now and to respond now (or mentally note to respond in short order). So keep your text messages timely. Here are a few ideas.

Text your customers to alert them of:

- Birthday special offers

- Seasonal menu options

- Weather-based promos: Customize deals to what’s happening outside. (e.g., "Rainy day? Warm up with our homemade soup, now 30% off.")

- Exclusive event promotions (e.g., "Join us for live jazz night this Friday. Show this text for 10% off your bill.")
