Providers

Trackly supports four SMS providers:
ProviderTierDescription
InfobipEssentialPrimary provider for most use cases
CMExpressFast provisioning, dual-provider support
TwilioStandardLegacy support
LimeStandardAdditional provider option
Dual-provider provisioning is supported for toll-free numbers — a single number can be provisioned across both Infobip and CM for redundancy and faster setup.

BYOC (Bring Your Own Carrier)

If you already have SMS provider credentials, you can use them directly with Trackly:
  1. Configure your provider’s webhook forwarding to point to Trackly
  2. Complete the 3-step webhook verification (credentials test → send test → webhook reply)
  3. Your BYOC list is ready to send
BYOC lists support all Trackly features (tracking, billing, compliance) but use your own provider rates.

Provisioning Process

Number provisioning requires a Paid plan ($19.99/month). Free plan users can bring their own numbers from any supported provider. Upgrade in Settings > Account Settings.

Multiple Numbers

You can have multiple sending lists/numbers for:
  • Different brands
  • Different use cases
  • Geographic targeting
  • Load distribution
Each list operates independently with its own contacts.

Number Health

Delivery Rate

Monitor delivery success:
  • 95%+ is healthy
  • Below 90% investigate issues
  • Below 80% may indicate problems

Carrier Feedback

Watch for:
  • Spam complaints
  • High opt-out rates
  • Carrier warnings
Discord alerts notify you of issues.

Troubleshooting

Check:
  • Is the list status active?
  • Are provider credentials valid?
  • Is there sufficient balance?
Possible causes:
  • Carrier throttling
  • Spam flag
  • Invalid configuration
Create an Urgent priority support ticket immediately from your dashboard (Support > New Ticket). Common causes:
  • Content violations
  • Spam complaints
  • Regulatory issues

Best Practices

“Marketing - Brand A” not “List 1”
Transactional and marketing on different numbers
Check delivery rates weekly
Don’t rely on a single number for critical sends
