7. SMS Credits and Usage
Checking Your Balance
View current usage in Settings → SMS Settings:
- Progress bar showing used/total credits
- Number of credits remaining
- Days until reset (billing cycle)
Running Low on Credits
When credits are low:
- A warning appears in the composer
- Consider upgrading your plan for more credits
- Or purchase overage credits at $0.10 each
Overage Handling
By default, overage is enabled:
- Additional SMS sends at $0.10 per credit
- To disable overage and stop sending when exhausted, toggle it off in Account & Billing settings
When Are Overage Charges Billed?
Overage is billed automatically:
- Monthly plans: Charged at month-end, or at $25 increments if you exceed that threshold
- Annual plans: Charged in $25 increments throughout the year, with any remainder at renewal
This keeps charges predictable and avoids large surprise bills, especially for annual subscribers.
8. Compliance and Opt-Outs
How Opt-Outs Work
With Two-Way SMS (Growth/Scale) If a customer texts STOP to your dedicated number:
- They are automatically opted out
- You cannot send them further SMS
- They can text START to opt back in
With Outbound-Only SMS (Starter) Since customers can't reply, first-contact messages include an opt-out link. When clicked, the customer is opted out automatically.
Best Practices
- Only SMS customers who have a business relationship
- Identify your business in messages
- Respect opt-out requests immediately
- Keep messages professional and relevant
