Why choose Line over other bulk SMS providers?
Real numbers, not short codes
Most bulk SMS services send from anonymous short codes or sender IDs that customers cannot reply to. Line sends from a real UK phone number that customers can save, text back, and call.
Two-way, not one-way
Traditional bulk SMS providers treat texting as a broadcast channel. Line gives you a shared inbox where your team can have real conversations with customers who reply to your bulk messages.
Built for small businesses
Enterprise bulk SMS platforms like Esendex require sales calls, contracts, and complex onboarding. Line is self-service — sign up, pick a number, and start sending in minutes.
SMS, calls, and WhatsApp in one place
Line is not just a bulk SMS sender. Your number also handles voice calls and WhatsApp, all in the same shared inbox. One number, every channel.
Bulk SMS messaging FAQ
Common questions about sending bulk text messages in the UK.
What is bulk SMS messaging?
Bulk SMS messaging means sending the same text message to many recipients at once. Instead of texting customers one by one, you write a single message and send it to a group — whether that is 10 people or 10,000. It is used for appointment reminders, marketing offers, payment nudges, and any scenario where you need to reach multiple people quickly.
How much does it cost to send bulk text messages?
With Line, each SMS costs 1p (one credit). There are no per-campaign fees, no platform charges on top, and no minimum spend. Your number costs from £1.70/month. Compare that to traditional bulk SMS providers that charge 3-5p per message plus monthly platform fees.
Is bulk SMS legal in the UK?
Yes, bulk SMS is legal in the UK provided you follow GDPR and PECR rules. For marketing messages, you need explicit opt-in consent from recipients and must include an opt-out option (e.g. 'Reply STOP to unsubscribe'). Transactional messages like appointment reminders and delivery updates have more flexibility under legitimate interest, but you should still inform customers.
Can recipients reply to my bulk messages?
Yes. Because Line sends from a real UK phone number (not a short code or no-reply sender), recipients can reply directly to your bulk text. Their replies appear in your shared team inbox, where anyone on your team can respond — turning a one-way broadcast into a two-way conversation.
How many messages can I send at once?
There is no hard limit on the number of recipients for a bulk SMS campaign with Line. Messages are sent quickly and reliably through UK carrier networks. For very large sends (thousands of messages), delivery is staggered over a few minutes to ensure high deliverability.
Do I need special software to send bulk texts?
No. Line runs entirely in the browser — there is nothing to install. Upload your contacts, write your message, and send. You can also use the mobile app to send bulk messages on the go. No special software, no technical setup, no IT team required.
What is the difference between bulk SMS and a short code?
Short codes are 5-6 digit numbers used by large companies for mass marketing. They are anonymous and recipients cannot reply naturally. Bulk SMS from Line uses a real UK phone number — customers see a genuine number they can save, reply to, and call. For small businesses, real numbers build far more trust than short codes.
Can I personalise bulk text messages?
Yes. You can personalise bulk messages with the recipient's name and other details so each text feels individual rather than generic. Personalised SMS messages get higher response rates and feel more professional.
