Send texts that feel more personal than bulk texts
A mass texting service lets you send a text to hundreds or thousands of contacts at once.
Personalization, photos and videos, trackable links and auto replies make every broadcast feel personal, so more people read it, respond and keep the conversation going.

Questions about mass texting
A mass texting service lets you send a text to hundreds or thousands of contacts at once. It’s also called text broadcasting or SMS broadcast. The best ones let you personalize each message, track clicks and automate replies.
You write your message, choose your audience and send. CallHub also lets you personalize with contact fields like first name, schedule your send, and set auto replies triggered by keywords.
Mass texting sends one message to many contacts at once. P2P texting assigns each contact to an agent who sends and answers messages one to one. Use mass texting for scale, and P2P for conversation. CallHub offers both.
Yes, when you have prior express consent. CallHub automates 10DLC registration, opt-out handling and consent tracking, and is CCPA, GDPR and HIPAA compliant.
Look for 10DLC and short code support, MMS, auto replies, CRM integrations that sync without CSV uploads, compliance certifications like SOC 2, and reporting on delivery, clicks and opt-outs. CallHub has all of these, and is SOC 2 and ISO 27001 certified, with the strongest security in the space.
Campaigns use it for get-out-the-vote reminders, fundraising (personalized donation asks that outperform email), voter outreach and volunteer coordination, like shift details and rally locations.
Yes. CallHub supports full MMS, including images, videos and GIFs. MMS messages drive up to 8X more clicks than plain SMS. Upload a video once and CallHub prepares the right version for every number you send from.
Videos can be up to 60 seconds. Clips up to 45 seconds keep their natural speed when compressed for MMS, and longer clips are sped up slightly (no more than 1.12x) so nothing is cut. Contacts on RCS get your original upload, up to HD.
An SMS broadcast is another term for mass texting. Use one for time-sensitive updates like event reminders, emergency alerts and fundraising deadlines.
Broadcast texting is sending one message to a large audience at once. SMS marketing is broader and includes broadcasts, drip campaigns and automated sequences. CallHub handles one-time sends and ongoing campaigns.
Yes. A mass texting service is one of the highest-converting fundraising tools available. Texts have a 98% open rate, far higher than email, and donation links sent by text consistently outperform other channels. You can personalize each message with the donor’s name, include a trackable donation link, and follow up with people who don’t respond using keyword auto replies.
Short codes are 5 or 6 digit numbers used for high-volume texting. They deliver faster and handle more messages than standard numbers, which makes them good for opt-ins and urgent broadcasts. CallHub supports short codes alongside 10DLC.
Yes. CallHub syncs with NationBuilder, NGP VAN, Blackbaud, Action Network and Salesforce. Contacts and tags sync automatically, and every broadcast is logged back to your CRM.
10DLC (10-digit long code) is a carrier-approved way to send campaign texts from standard phone numbers. It improves deliverability and lowers spam filtering. CallHub handles the registration for you.
On CallHub’s pay-as-you-go Essentials plan, texts cost 1.9¢ per segment and MMS costs 4.8¢ per message. Texts people send to you are free, and you get $6 in free credits to start.
