Avoiding Carrier Filters in SMS Marketing


Avoiding Carrier Filters in SMS Marketing

We recently received the following message through our ‘Contact our Experts’ form.

“We have been using a different service for SMS marketing, and a lot of our messages are getting blocked by filters. Can you guys get us passed the carrier filters?”

Fortunately, this is something we see every day, and have a team in place to guide our customers through the tricky landscape of carrier filters.

What are carrier filters?

Mobile subscribers who receive an overload of spam SMS messages often feel that their only option is to find a new carrier. Rather than allow subscribers to churn, carriers like AT&T, Vodafone, and Orange choose to block out spam SMS messages. To do so, they set up filters blocking certain messages from getting through.

These filters range from keywords that prevent messages from getting through, to complex, machine-learning filters that shield customers in real-time from being overwhelmed by unwanted messages. Often times filters are activated by customer complaints, causing future messages emanating from that number to filtered out. Filters can also block high-volume senders, even if the message is innocuous.

Carriers protect their filters as a closely guarded secret, to prevent spammers from learning how to sidestep these consumer protections. There is no way to know with certainty if a message will get through. Unfortunately, unlike email where a recipient can “whitelist” a specific sender, carrier filters don’t take user preferences into account while blocking a message from getting through.

Best Practices to Avoid Filters

There are two primary reasons why messages get blocked: spammy content and high volume sending. Here are some of the tools and tricks we recommend you use to help your messages arrive at their destination.

Require Opt-In

When SMS recipients opt in, it is much less likely that they will complain when they receive your texts.

Offer Opt-Out

When recipients have a way to stop receiving your messages, they tend to opt out rather than file complaints against you.

The Message Itself

Sending a message to customers should provide a good customer experience. The message should not be too long and should contain information that is immediately useful. Messages that encourage recipients to respond are very effective, as they demonstrate value that you are delivering to the customer.

Do Not Include…

Overly capitalized SMS messages look like spam, while aggressive language often leads to complaints. Avoid overly long messages, and cut down on hyperbole like 100% guaranteed, completely FREE, or no charge. These tend to be filtered.

Use Short Codes

Short codes are 5-6 digit telephone numbers that are used to send out SMS messages. These numbers are pre-approved by carriers for high-volume SMSing, and can be used for marketing and promotions, alerts and notifications. These are ideal for businesses that need to send out high-number of messages over a short time period.

One Last Thought

There are no guaranteed ways to completely avoid filters. However, to help protect our customer’s SMS marketing budget, MessageWhiz offers a risk-free revenue share pricing model, where you only pay  when you’ve achieved your desired campaign results. That way, you won’t pay to send out messages that carriers filtered out.

4 Great SMS Uses for the Gaming and Gambling Industry


4 Great SMS Uses for the Gaming and Gambling Industry

Over 50% of all gamers who spend money on video games are Millennials between ages 18-34. They are deeply entrenched in the digital lifestyle and prefer to communicate with their trusted brands through SMS over any other channel. This combination creates the perfect storm for gaming companies utilizing SMS messages in their marketing and gameplay strategy.

Protecting Gamer Accounts

Fraud is a considerable threat for gamers and online gamblers. It is a world where billions of dollars each year switch hands instantly through in-game purchases and betting, as the game steadily moves forward without pause. Criminals hack into accounts, giving them access to their victim’s in-game credit card or PayPal account.

Using SMS as a 2-factor authentication tool (2FA) helps protect players and their assets. Accounts become accessible only through a combination of user name-password and a second code sent to the user’s mobile device via SMS.

Enhancing Sales Through Triggers

As players progress through games, their challenges typically increase. Savvy gaming companies can assign triggers indicating a need for a new item in the near future, and have their system automatically generate an SMS promoting the in-game purchase. The SMS can include a link to a video, where players can see the benefits provided by the in-game purchase. When they do reach the stage where the item is useful, they will have already been prepped to make the purchase.

Triggers can also be used to remind players that a scheduled event is coming up. If the system notes that other members of their team have come online, individuals can receive an SMS notification, telling them that their team is assembling.

New Levels and Launches

As new games come online game developers can send bulk SMS alerts to their players promoting the game. The messages can include video links, giving players a preview of the excitement that awaits them.

This method is especially useful when new levels or worlds are added to existing games. Sending out text messages with video links to players who have moved on to other games is an effective way to bring them back into a game.

SMS for Gamblers

Gambling sites can use an SMS messaging service to alert customers of changing betting opportunities. Triggers can be set up alerting users that odds are changing, or that new betting opportunities have become available.

Many casino companies use SMS to manage their loyalty programs and communicate regularly with their regular gamblers by reminding customers to top up their accounts,  upcoming tournaments, events, and competitions or special chip promotions. SMS messages can also be used to send out betting tips, and SMS short codes can attract new users who text in by offering a tip of the week.
