All plans include unlimited messages and start with a 14-day free trial. No credit card required.

Yes. Every new account gets a 14-day free trial with Starter-level access (unlimited messages, up to 250 new contacts/month). No credit card required. After 14 days, choose a plan to continue sending. Your account stays active and you can still log in, view message history, and upgrade at any time.

Messages are unlimited on all plans — the limit is on how many new contacts you can reach per month. Once you hit your new contact limit, you can still message all your existing contacts without any restriction. Upgrade to a higher plan to reach more new contacts.

Yes. Upgrade or downgrade instantly from your dashboard. When you upgrade, you get immediate access to the new plan's limits. When you downgrade, the change takes effect at the start of your next billing cycle.

A new contact is a phone number you have never messaged before. Once you message someone, they become an existing contact — and you can message them as many times as you want, on any plan, with no limits. Only the first message to a new number counts against your contact quota.

Twilio charges $0.0079 per SMS + $1/month per phone number + 10DLC registration fees ($15–25 per campaign). senderZ offers unlimited messages on flat monthly plans with no per-message fees, no number fees, and no 10DLC registration required. For most small-to-medium businesses, senderZ is significantly cheaper.
