SMS Marketing

Send restock alerts, offers, and reminders through your SMS provider. Choose who should get the text, send it now or schedule it, and see how many messages went out.

Requires a connected SMS provider. Provider messaging charges apply.

From the Sendwo customer community

From provider setup to your first broadcast

Start with a test group so you can check the sender, the text, and the report before sending to a larger audience.

01

Connect an SMS provider

Save its credentials and sender details in an SMS profile.

02

Prepare the campaign

Choose the SMS profile and subscriber list, write your message, and set the send time.

03

Check the results

Open the report and compare the targeted and sent counts.

SMS provider setup

Send through the provider you already use.

Open Integrations and choose SMS API to create a reusable SMS profile. Give it a recognizable name, choose your provider, and enter the credentials and sender details it requires.

  • Choose a supported provider. Connect a provider such as Twilio, Plivo, or Vonage (Nexmo).
  • Pick the right sender. Use the approved number or sender ID from your provider. Select the saved SMS profile when you build a campaign.

SMS broadcasting

Write it once. Send it when it matters.

In SMS Broadcast, choose your SMS profile and the connected WhatsApp bot that supplies the subscriber list. Write the text, add a first-name or last-name variable when useful, and check Targeted Reach before sending.

  • Check the destination numbers. Review country-code formatting so you can catch mistakes before the send.
  • Pick a send time and pace. Send now or schedule by time and time zone. Set a delay between messages when needed to match your provider’s throughput.

Custom HTTP POST integration

Keep your regional or in-house SMS gateway.

If your gateway accepts a compatible HTTP POST request, create an HTTP POST profile and enter its send endpoint. Use the parameter names your provider expects.

  • Map the request. Use Fixed for static values, To for the recipient number, and Message for the campaign text.
  • Test before sending. Use Test response to check the request, then verify a test SMS on a phone. If the API requires headers the profile cannot set, your team may need a server-side adapter.

Campaign reporting

Check what went out after each send.

Open a campaign report from SMS Broadcasting to review its status, the targeted audience, the selected SMS API, and the count marked Sent. Check recipient timestamps and response details when the integration provides them.

  • Compare targeted and sent. See how far the campaign progressed and which records to review when the counts differ.
  • Confirm delivery with your provider. For handset delivery, check the provider’s delivery status where available. Sent and Sent at describe sending activity.

When a short text is enough

Give customers the update they need and a clear next step.

Restock alerts and offers

Tell shoppers an item is back, share the offer deadline, and give them one link to act on.

Appointment reminders

Give customers the date, time, and location before their visit.

Pickup and service updates

Let customers know when an order is ready or when a service schedule changes.

SMS Marketing FAQs

Do I need an SMS provider to send campaigns?

Yes. Connect a supported SMS provider or a compatible custom gateway and set up an approved sender where required. Your SMS provider’s charges are separate from your Sendwo plan.

Does the SMS go out through WhatsApp?

Your connected WhatsApp bot supplies the subscriber list for this workflow. The selected SMS provider sends the text to the recipient’s phone number. Check that your contacts are eligible to receive SMS for that purpose.

Can I personalize and schedule an SMS broadcast?

Yes. Insert a first-name or last-name variable when the contact has that information. Send now or choose a scheduled time and time zone. Check the sender, text, and country-code formatting on a test phone first.

Can I connect my own SMS gateway?

You can connect a compatible HTTP POST gateway. Enter the endpoint, map the required parameters, and use Test response to check the request. A gateway that needs unsupported headers or request formatting may require an adapter.

What can I see in an SMS campaign report?

The report shows campaign status, targeted count, SMS API, sent count, and available recipient details such as chat ID, name, send time, and provider response. Check the provider for delivery confirmation when available.

Who should receive a promotional SMS?

Use recipients who have agreed to receive the type of message you plan to send. Follow the opt-out and sender requirements that apply to your destination and provider, and honor opt-outs before your next send.
