Create and edit an SMS campaign

SMS campaigns have their own short editor that shows how long your message is and how many credits it will use.

Updated September 21, 2026 · 1 min read

In this article you will write an SMS campaign, add a link or discount, and understand the credit counter.

Before you start

  • An approved SMS sender (Settings → SMS sender identity).
  • SMS credits in your account.
  • SMS subscribers, that is, contacts who agreed to receive texts.

Steps

  1. Go to Campaigns → Create campaign and choose SMS.
  2. Write the message. The counter below the text shows the number of characters and how many credits each text will cost. Longer messages are split into several parts and cost more.
  3. Optionally add a discount code or a link to your store. Links are shortened automatically.
  4. Continue to Review, choose the audience and send or schedule it, as with an email campaign.
Use the SMS editor’s segment and credit estimate after editing the message. Personalization, links and some characters can change its length and cost.
Texts are only sent to countries you have enabled in Settings → SMS sender identity → Countries. Contacts elsewhere are skipped.
