Send SMS online
From your browser, your AI or your code
A complete SMS gateway with scheduling, personalization, two-way replies and full delivery insight. No RCS required.
You don't need rich cards and carousels to get value out of SendRCS. Use it as a straightforward, reliable SMS gateway: write and send text messages from your browser, let your AI assistant send them for you, or plug our API into your own systems. Personalize every message, schedule campaigns for the perfect moment, receive replies on a virtual number, and follow every delivery in real time.
An SMS gateway that just works
SMS is still the channel that reaches everyone. No app to install, no internet required, read within minutes. Whether you're confirming an order, reminding a customer about an appointment or announcing a sale, a text message gets seen.
SendRCS gives you three ways to send it: a clean web interface your whole team can use, an AI connection so your assistant can handle the sending for you, and a REST API for your developers. Same contacts, same statistics, same message log, whichever way you send.
And when you're ready for more than plain text, RCS is already built in. Upgrade a campaign to rich cards, images and buttons whenever you like, with the same platform and the same API.
Everything you need to send SMS
Browser, AI and API - three ways to send, with one set of contacts, statistics and logs behind them.
Send SMS from your browser
Compose your message, pick a contact, a group or paste in a list of numbers, and send. Merge fields like {{contact_first_name}} personalize every message automatically, a live counter shows characters and SMS segments as you type, and the exact price is shown before you hit send. Save messages as templates and reuse them across campaigns.
Schedule SMS for later
Write now, send later. Pick the date, time and timezone, and your campaign goes out exactly when it should, even if you're asleep. Scheduled messages appear in the message log, where you can review or cancel them any time before they're sent.
Personalize with merge fields
Write one message, send a thousand personal ones. Drop in fields like {{contact_first_name}}, {{company_name}} or any custom field you've created, and each recipient gets a message written just for them. Merge fields work everywhere: browser, AI and API.
Unsubscribe links, built in
Add the {{unsubscribe_link}} merge field and every recipient gets their own personal opt-out link, no setup required. Opted-out contacts are flagged automatically so they're never messaged again, and every unsubscribe shows up in your statistics with its source and campaign.
Virtual numbers in your country
Rent a local virtual number on a simple monthly subscription and use it as your sender. Your messages come from a real number your customers can text back, and you can hold several numbers across different countries from the same account.
Two-way SMS inbox
When customers reply, their answers land in a real-time inbox, organized as one conversation per contact. Push notifications alert you on desktop and mobile the moment a reply arrives, your team shares the same view, and any conversation can be exported to CSV.
Read moreSend SMS via AI (MCP)
Connect your AI assistant to SendRCS through MCP and let it do the work: "Send a reminder to everyone in the Friday group at 9 tomorrow" becomes a drafted, scheduled campaign. The AI can look up contacts, personalize messages, schedule sends and check delivery, and with approval mode on, nothing goes out until you've reviewed a preview and said yes.
Read moreSend SMS via API
A clean REST API for developers: create an API key in your settings, and you're sending in minutes. Single messages or campaigns, merge field personalization, timezone-aware scheduling and delivery status, all documented at docs.sendrcs.eu.
Read moreSMS statistics
See how every campaign performs: sent, delivered and failed counts, delivery rate, message volume over time and the times of day your audience responds best. Filter by campaign, date range or source, follow your costs per country, and keep an eye on unsubscribes as they happen.
SMS log
Every message, searchable. Filter by status, date, campaign or direction, search by name or number, and see segments, encoding and cost per message. Retry a failed message, cancel scheduled ones in bulk, and export the lot to CSV or Excel when you need a record.
The SMS gateway your AI can use
SendRCS speaks MCP, the open standard that connects AI assistants to real tools. Link your assistant to your SendRCS account with a secure browser login, and it can manage contacts and groups, draft and personalize messages, schedule campaigns and read delivery results, all through plain conversation.
You stay in control. With approval mode on (the default), every message the AI prepares comes to you as a preview first: you see exactly what will be sent, to whom, and what it costs, and nothing leaves the platform until you approve it. Connected AI clients are listed in your settings, and you can revoke access with one click.
Send and schedule SMS campaigns by describing them in plain language
Approve every send from a preview, or allow trusted automations to run on their own
Works with any AI assistant that supports MCP
One API for one message or ten thousand
The SendRCS REST API is designed to be boring in the best way: predictable endpoints, clear errors and honest delivery status.
Send single messages or full campaigns with one integration
Personalize with merge fields, resolved per recipient at send time
Schedule with ISO 8601 timestamps and IANA timezones
Track delivery per message and group sends under campaign names for statistics
Manage API keys from your dashboard: create, disable and delete in seconds
Full reference, guides and examples at docs.sendrcs.eu. And because it's the same API that powers RCS, adding rich messaging later doesn't mean a new integration.
Sending in minutes
Four steps from signup to your first delivered campaign.
Create your account and sender
Use your company name as the sender, or rent a virtual number your customers can reply to.
Add your recipients
Import contacts, organize them in groups, or just paste in numbers.
Send or schedule
From the browser, through your AI assistant, or via the API. The price is always shown before you send.
Follow the results
Live statistics show delivery and engagement, and the message log keeps every message searchable and exportable.
Sending SMS with SendRCS, answered
Can I use SendRCS just for SMS, without RCS?
Yes. Everything on this page works with plain SMS: sending, scheduling, two-way replies, AI, API, statistics and logs. RCS is there when you want it, never required.
How is an SMS priced?
Per message segment, with the exact price shown before every send. A standard SMS holds 160 characters per segment; emojis and special characters switch the message to Unicode at 70 characters per segment. The live counter shows both as you type, so there are never surprises on the invoice.
Can I send bulk SMS to a whole list?
Yes. Send to contact groups or pasted number lists, with merge fields personalizing each message individually. Large sends are automatically paced for reliable delivery.
Can I schedule messages in a different timezone?
Yes. Pick any timezone when scheduling, and the platform handles the conversion. Scheduled messages can be reviewed and cancelled from the message log until the moment they go out.
Can customers reply to my messages?
Yes, when you send from a virtual number. Replies arrive in a real-time inbox as one thread per customer, with push notifications so your team never misses an answer.
Is it safe to let an AI send SMS?
Yes. The connection uses a secure browser login you can revoke at any time, and with approval mode on, every message needs your explicit go-ahead from a preview before it's sent. You choose if and when to allow fully automatic sending.
Where do I find the API documentation?
At docs.sendrcs.eu, including guides for both the REST API and the MCP connection for AI assistants. API keys are created in your account settings in seconds.
How do I stay compliant with marketing rules?
Add the built-in {{unsubscribe_link}} merge field and every recipient gets a personal opt-out link. Unsubscribes are tracked in your statistics, and opted-out contacts are flagged so you don't message them again.
