SMS has one of the highest open rates of any marketing channel — most texts are read within minutes of delivery. An SMS blast lets you reach your entire list or a targeted segment with a single send. No ad spend, no algorithms, and no guessing whether your message was seen.
Send an SMS blast to your contact list

​
Why this matters

SMS messages have a 98% open rate vs. email’s 20%, and most texts are read within 3 minutes of delivery. An SMS blast generates engagement — and often direct sales — almost every time you send one. It is one of the fastest ways to drive immediate action from your existing contact list.

How to send an SMS blast

1

Go to SMS Marketing

Navigate to Marketing > SMS > Campaigns and click New Campaign.
SMS campaigns section
2

Name your campaign

Give your campaign a clear internal name — for example, “April Event Reminder — SMS Blast” — for easy identification later.
3

Choose your recipients

Select who receives this SMS:
  • Entire list: Send to all contacts in a contact list
  • Smart list: Target a filtered segment — for example, contacts tagged “VIP” who have not booked in 30 days
  • Specific contacts: Manually choose individual recipients

4

Write your message

Type your SMS in the message field. Best practices:
  • Keep it concise — SMS works best under 160 characters
  • Personalize with merge tags like {{contact.first_name}}
  • Lead with the value offer, then include a clear call to action with a link
  • Add a trigger link to track clicks and trigger automated follow-up
  • Always include opt-out language: “Reply STOP to unsubscribe”
A proven SMS formula: “Hey [First Name], [value offer]. [Link]. Reply STOP to opt out.” — concise, personal, and compliant. Start with the name to ensure they know it is meant for them.
5

Choose your send timing

Select when to send:
  • Send immediately: Delivers right away
  • Schedule: Set a specific date and time
  • Drip send: Spread delivery across a time window in batches
SMS send timing options
6

Send or schedule

Review your message and recipients, then click Send or Schedule. The campaign will appear in your list with its current status.
7

Track results

After delivery, check your campaign statistics:
  • Delivered: How many messages were successfully delivered
  • Failed: Messages that could not be delivered
  • Clicked: How many contacts clicked a link in the message
Replies from contacts appear automatically in the Conversations inbox.

Key points

US carrier regulations require that every outbound SMS marketing message include opt-out language (“Reply STOP to unsubscribe”). Failing to include this damages your sender reputation and can result in number flagging. The platform can append this automatically — check your SMS settings.
To send SMS blasts to US contacts, your number must be registered under A2P 10DLC. Unregistered numbers have significantly reduced deliverability. See the A2P 10DLC Registration guide.
Smart Lists give you precise control over who receives your SMS. Filter by tags, custom fields, location, engagement, or any contact property. Better targeting means higher engagement and fewer opt-outs.
