What is Mass Text Messaging?


A mass text message is a one that is sent to a large list of contacts/constituents at once by an organization or business. Mass text messaging lets you send a single, personalized text message to entire groups of people, big or small.

Scheduling a quick mass text can save you the time and effort of having to go through your entire list of contacts and shooting them messages individually. 

Depending on your objectives, there are a ton of ways you can use mass texting. For example, sending event invitations to collect RSVPs and event reminders, GOTV texts, fundraising asks, sale notifications, and promotional codes. Those are just some of the ways organizations are using mass texts to communicate with their audiences.

Benefits of Mass Text Messaging


There are so many ways organizations of all shapes and sizes are using mass texting, from political campaigns and advocacy groups to nonprofits and businesses. And for good reasons.

98% of text messages are opened and read. It’s easy to understand why organizations are quickly adopting text messaging as their primary medium to connect with their audiences.

It’s all possible with personalized mass text messages at scale.

How mass texting works

Add Contacts

Upload the spreadsheet with your list of contacts. You can also connect your CRM to import contacts.

Create campaign

Create your Mass Text messaging campaign, then select the contact list you want to send your text message to.

Draft message

Create your text message, personalizing it with custom fields (merge tags) like {{first-name}}.

Set a time

All that’s left is to schedule your message to go out whenever you want it to.

Is it legal to send Mass Text Messages?

The short answer: Yes. But in order to be able to start mass texting large groups of people, you need to get their explicit permission first.

That means telling people why you are collecting their contact details before sending them texts.

If you already have a list of people who have agreed to your text messages, you can simply import it to your software to start sending them messages with your short code.

Stay compliant by:

- Not sending unsolicited messages.

- Sending a confirmation message on opt-in

- Making it easy for people to opt-out

- Not sending inappropriate content

- Not texting at odd hours

- Not sending texts too often

Building a Contact List for Mass Text Messaging

There’s no need to worry if you don’t already have a list of contacts that you can send text messages to. One way to get people subscribed is by asking them to opt-in via a text message.

All you would need to do is rent a short code or a normal number and a keyword from a text messaging service. When people text the keyword to your short code, they get added to your contact list. You can then send mass texts to the people on the list.


Use keywords to sign up new contacts

Rent number and keywords

Rent a short code or 10-digit number and a keyword for your opt-in campaign.

Promote your keyword/number

Ask your audience to subscribe to your contact list by texting in the keyword to your number.

Collect contact information

Personalize your texting campaigns with additional details like name, email, zip code from subscribers collected using automated followups. 

Create mass texting campaigns

Once your contacts had been added to your phonebook, you’re all set to start sending them mass text messages. Sign up to try SMS Opt-ins for your campaign.
