Line vs traditional email to SMS gateways

Traditional email-to-SMS gateway providers are built for enterprise IT teams with months-long onboarding. Line is built for small businesses.

Self-service, not enterprise contracts

Traditional SMS gateway providers require a sales call, an enterprise contract, and a developer to configure SMTP relay settings. With Line, you sign up online, get your gateway address instantly, and send your first SMS from email in under five minutes — no IT team, no minimum commitment.

A real UK number, not a shared short code

Most email-to-SMS gateways deliver messages via shared short codes or anonymous sender IDs that recipients cannot reply to. Line sends your SMS from a dedicated UK mobile, national, or local number that customers can save and respond to directly.

From £1.70/mo, not enterprise pricing

Enterprise SMS gateway providers charge per-message rates of 3–8p plus monthly platform fees with minimum spend commitments. Line starts at £1.70/month with transparent per-message pricing and no minimum spend — the same gateway technology at a fraction of the cost.

Two-way: replies come back to your inbox

Traditional gateways handle outbound delivery only. With Line, when a customer replies to your SMS, that reply is automatically forwarded to your email inbox. Your email client becomes a full two-way SMS channel without any additional setup.

Email to SMS FAQ

Common questions about sending SMS via email.

How do I send an SMS via email?

With Line, you get a personal email-to-SMS gateway address (e.g. sms@yourbusiness.useline.io). To send an SMS, compose an email in any client — put the recipient's mobile number in the To field as a special address (e.g. 447700900123@sms.useline.io), write your message in the email body, and send. Line converts the email into an SMS and delivers it from your UK business number within seconds.

What is an email to SMS gateway?

An email to SMS gateway is a service that receives emails and converts them into SMS messages. You send an email to a special address containing the recipient's phone number, and the gateway delivers the message as a text. Line provides an email-to-SMS gateway built into every account — no separate contract or technical setup required.

Is there a free email to SMS service in the UK?

Truly free email-to-SMS services typically use shared numbers, carry advertising, or impose strict message limits. Line offers a genuine email to SMS service from £1.70/month with a dedicated UK phone number and no artificial message caps. There is no free tier, but at £1.70/month it is significantly cheaper than traditional SMS gateway providers.

Can I send SMS from Outlook or Gmail?

Yes. Line's email-to-SMS gateway works with any email client, including Outlook, Gmail, and Apple Mail. There is no plugin or add-in to install. You simply compose an email using the standard To field format, and Line handles the conversion and delivery. Replies from the recipient come back to your inbox as well.

How does email to SMS pricing work?

Line charges a monthly subscription starting at £1.70/mo for your UK business number. Outbound SMS are charged per message at standard UK rates — typically 3–5p per segment. There are no setup fees, no minimum spend, and no enterprise contracts. Full pricing is on the pricing page.
