Turn one text into a list that never stops growing

The process is incredibly simple for both you and your subscriber:

• Choose a Keyword: Inside your CallHub account, you reserve a unique keyword (e.g., “ACTION,” “DONATE,” or “STANDWITH”).

• Promote It: You share your keyword and number everywhere—on your website, in emails, and on social media (e.g., “Text ACTION to 123-456 to join our alerts!”).

• They Text In: A person sees your promotion and texts the keyword to your number.

• They’re Subscribed!: CallHub’s platform automatically receives the text, captures their phone number, and adds them to your chosen contact list.

Our platform manages this entire workflow, making it one of the most reliable text to join services for growing your audience instantly.

An SMS opt-in is your audience’s explicit permission for you to send them text messages. It is the single most important part of your texting program for two key reasons:

• It’s a Legal Requirement: In most countries, it is illegal to send bulk text messages to people who have not given you provable consent to contact them.
• It Builds a High-Quality List: An opt-in list is made of people who want to hear from you. This leads to much higher engagement, better response rates, and a stronger, more trusting relationship with your community.

An opt-out is the method you must provide for subscribers to easily stop receiving your messages at any time.

It works automatically through common keywords. If a contact replies to one of your messages with “STOP,” “QUIT,” “END,” “CANCEL,” or “UNSUBSCRIBE,” CallHub instantly recognizes the command. It will automatically mark that contact as “Opted-Out” and send them a final confirmation message, ensuring they receive no further texts from that campaign. This is a required feature, and it’s handled for you.

You can set up a powerful text to join campaign in CallHub in just a few minutes:

1. Log in to your CallHub dashboard and navigate to “Keywords.”
2. Click to create a new keyword, choose a word that’s simple and memorable, and assign it to a phone number.
3. Link this keyword to a specific contact list (e.g., “New Website Subscribers”).
4. Create your automated welcome message and conversation flow.

That’s it! Now you’re ready to promote your keyword.

Yes, and you absolutely should! This is a best practice and a key feature of our text to join service.

The moment someone texts your keyword, CallHub can instantly send an automated reply. This first message is crucial for:

• Confirming their subscription.
• Delivering any promised incentive.
• Including all the required compliance disclosures (like “Msg&Data rates may apply…”).
• Engaging them further. You can even use this reply to ask for more information, like, “Thanks for joining! Reply with your EMAIL to get our newsletter, too.” This makes it a perfect tool to use text to join to build your contact list.
