Bulk SMS: Group Text Sender

Send one SMS to hundreds of contacts, straight from your phone. Group SMS is a bulk SMS app for mass texting: build groups, import lists, personalize every message and see exactly what it costs — no SMS gateway, no per-message fees, no contacts uploaded anywhere.

GROUP TEXT MESSAGING MADE SIMPLE

Create contact groups for clients, staff, teams, classes, tenants or events, then send one text message to everyone. Your phonebook stays exactly as it is: Group SMS never edits your contacts.

BULK SMS FROM LISTS, WITHOUT SAVING CONTACTS

Import hundreds of numbers from a CSV or VCF file and text them without cluttering your address book. Separator, encoding and columns are detected automatically, duplicates are skipped, and any row that cannot be read tells you why. Ideal for customer lists, members, leads and one-off campaigns.

PERSONALIZED MASS TEXT MESSAGES

Use , and in your templates and every recipient gets a message written for them. Bulk texting that doesn't read like bulk texting.

SMS MARKETING CAMPAIGNS

Spread a large text blast over several days in controlled batches, with a daily reminder. Reach a big audience without fighting carrier limits.

SCHEDULED SMS

Plan a text for later — once, or repeating daily, weekly or monthly. Appointment reminders, shift rotas, payment due dates, birthdays.

TEMPLATES AND MMS ATTACHMENTS

Write once, reuse forever. Attach photos or PDF files and send them as MMS.

DELIVERY TRACKING AND STATISTICS

See how many messages actually went through, your SMS per month, your most used groups and a real cost estimate for every bulk SMS send.

KNOW WHAT YOU ARE PAYING

The composer counts real SMS segments, not just characters, and warns you when a single emoji cuts your limit from 160 to 70 characters. No more surprise bills.

BLACKLIST AND OPT-OUT

Keep a blacklist of people who asked you to stop. They are skipped automatically in every group, list, template, scheduled message and campaign.

SMART CLEANER

Find and remove duplicate numbers and invalid entries from your lists in one pass.

BACKUP AND RESTORE

Export groups, lists, templates and settings to a single file and restore them on any device.
