Bulk SMS

Send SMS campaigns to contact lists using templates, with delivery tracking and analytics.

The Bulk SMS module lets you send text message campaigns to groups of contacts at once. Build reusable templates with personalization, target specific audiences, schedule sends, and track delivery and engagement for every campaign.

Bulk SMS analytics: total sent, delivery rate, click rate, and recent campaigns.

Overview

Bulk SMS is designed for outbound text messaging at scale - appointment reminders, promotional offers, event announcements, and other time-sensitive communications. Messages are sent through your connected phone number and delivery status is tracked for every recipient.

SMS Templates

Templates let you create reusable messages that your team can send consistently.

Creating a Template

Navigate to Bulk SMS and open the Templates tab
Click New Template
Enter a template name and compose your message in the text area

Merge Fields

Insert personalization tokens to tailor each message to the recipient:

Contact fields - First name, last name, phone, email, company, and any custom fields
Custom values - Business name, address, website, and other values defined in settings

Merge fields appear as tokens like {{firstName}} in the template and are replaced with each contact's actual data when the message is sent.

Character Count

The composer displays a live character count and segment estimate as you type:

Encoding	Characters per Segment
Standard (GSM-7)	160 characters
Extended (Unicode)	70 characters

Messages longer than one segment are automatically split and reassembled on the recipient's device. The cost per message increases with each additional segment, so the counter helps you keep messages concise.

Preview

A phone mockup on the right shows how your message will look to the recipient. Merge fields are replaced with sample data so you can check formatting and length before sending.

Sending a Bulk SMS

Selecting an Audience

Build your audience from saved contact lists and segments.

Choose who receives your message:

All contacts - Every contact with a phone number on file
Segment - Target a saved segment for more precise targeting
Tag - Send to contacts with a specific tag

The audience preview shows the total number of recipients and a sample of matching contacts. Contacts without a phone number are automatically excluded.

Choosing a Template

Select a saved template or write a one-off message directly in the composer. If you use a template, you can customize the content before sending without changing the original template.

Scheduling

Option	What It Does
Send Now	Begins delivering messages immediately in batches
Schedule	Pick a date and time - the campaign is queued and sent automatically

For scheduled campaigns, the status changes to Scheduled and you can cancel or reschedule before the send time arrives.

Review and Confirm

Before sending, a confirmation screen shows:

The message content with a character and segment count
The audience size and any contacts that will be skipped
The estimated send time
The sending phone number

Click Confirm and Send to start delivery.

Analytics

After a campaign is sent (or while it is sending), the analytics view tracks delivery and engagement.

Delivery Rates

Key delivery metrics for each campaign:

Metric	What It Measures
Sent	Total messages dispatched
Delivered	Successfully reached the recipient's device
Failed	Could not be delivered (invalid number, carrier rejection, etc.)
Delivery Rate	Delivered divided by sent, shown as a percentage

Per-Campaign Performance

A table lists all campaigns with their name, send date, audience size, delivery rate, and status. Click any campaign to view its full recipient list and per-contact delivery status.

Charts and Export

Visual charts show delivery volume per campaign and a breakdown of failure reasons. Export recipient details as a CSV file including contact name, phone number, delivery status, and timestamp.

Compliance

Bulk SMS includes built-in safeguards to help you stay compliant with messaging regulations.

Opt-Out Handling

When a recipient replies with a standard opt-out keyword (such as STOP, UNSUBSCRIBE, END, or QUIT), they are automatically added to the suppression list and receive a confirmation. Future bulk SMS campaigns skip suppressed contacts. Recipients can resume messaging by replying with a start keyword (such as START or SUBSCRIBE).

Suppression List

The suppression list shows all contacts who have opted out of SMS communications:

View the contact name, phone number, opt-out date, and reason
Manually add contacts to the suppression list if needed
Remove a contact from the list to re-enable messaging (only if they have re-consented)
Import or export the suppression list as CSV

Best Practices

Always identify your business in the message so recipients know who is texting them
Include opt-out instructions (e.g., "Reply STOP to unsubscribe") in every campaign
Respect quiet hours - avoid sending messages early in the morning or late at night
Only message contacts who have given explicit consent to receive texts
