// Why this works

Your messaging bill grows every time your business does.

At Twilio's $0.0083 a message, every customer you text adds to the bill. Switching feels risky when new 10DLC campaigns can sit in carrier review.

Carrier-Ready Review

A messaging bill you can predict, from people you can reach.

  • A rate that only moves down

    Blocx never raises your rate, and it drops as volume grows.

  • No surprise bills

    A hard monthly cap stops sending, and the API blocks duplicate messages.

  • Fixes from the people who build Blocx

    Scale plans include a private Slack channel with our dev team.

Built for

  • You want a hard monthly spend cap that stops sending.
  • You want a private Slack channel with Blocx engineers.

Who it's not for

  • You don't need a limit on monthly messaging spend.

Frequently Asked Questions

What does the 48-hour 10DLC approval guarantee mean?

You'll meet one-on-one with a Blocx 10DLC expert and follow their advice on your submission. Do both, and we guarantee carrier approval in 48 hours.

Do you work with firearms and other restricted businesses?

Yes, on Scale, where a dedicated compliance contact reviews your use case. Carriers decide final approval, so restricted senders sit outside the 48-hour guarantee.

Will my rate ever go up?

Our rate never goes up and only drops as you grow. Carriers can raise their pass-through fees, but our own rate stays locked.

Does Blocx handle 2FA verification?

Blocx Verify runs $0.035 per successful verification with SMS delivery included, while Twilio Verify lists $0.05 plus delivery.

How much work is the switch from Twilio?

Plan on real engineering: swap API calls using our SDK and re-point webhooks, with 1:1 onboarding at every step.

What does Scale cost, and is there a contract?

Scale has a $1,000 monthly minimum on an annual contract, and the minimum doesn't start until day 31.

What if a bug in our code sends the same text twice?

Blocx blocks duplicate messages at the API level, and your monthly spend cap stops all sending once you reach it.
