Bulk SMS UK — mass texting for small businesses

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.

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.

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.

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.

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.

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.

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.

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.

To send bulk SMS in the UK with Line: sign up and pick a real UK number, import your contact list as a CSV or build it over time, write your message (with optional personalisation), and hit send. Replies land in your shared team inbox. No specialist software, no IT team, and no minimum send volume required. You can send your first bulk SMS in under 5 minutes.

A mass texting service lets you send the same SMS to many recipients at once — sometimes called bulk SMS or mass SMS sender. You write one message and it is delivered to your entire contact list simultaneously. A good mass text service also handles replies so you can have individual follow-up conversations, not just one-way broadcasts. Line does both from the same real UK number.

Truly free bulk SMS services in the UK are rare and typically limited. They often use shared sender IDs, cap messages per day, or attach promotional footers. Line is not free — texts cost 1p each — but the cost is among the lowest available for a legitimate UK bulk SMS service with real numbers and two-way messaging. There is no monthly minimum spend and no contract.
