SMS
SMS marketing,compliance first.
Bulk SMS reaches nearly every phone on earth, and nearly every country regulates it. CaviusConnect sends your campaigns through carrier-registered routes with TCPA, 10DLC, and DLT checks built into the send path, so scale never comes at the cost of compliance.
01What you get
Everything bulk SMS needs to be.
01
Campaigns & broadcasts
Segment your contacts and send bulk SMS campaigns with scheduling, throttling, and per-message delivery status.
02
Two-way messaging
Replies land in the unified inbox as one thread per contact, alongside their email and WhatsApp history.
03
Codes & sender IDs
Carrier-registered short codes, long codes, and alphanumeric sender IDs, with TCR and DLT registration handled for you.
04
Delivery reporting
Delivery, engagement, and block reasons for every message, including exactly which compliance rule stopped a send.
05
Segmentation
Build audiences from contact attributes and consent state, so a promotional list can never include someone who only opted into service messages.
06
API & SDKs
Send programmatically over REST with typed SDKs for Node, Python, and Go. The dashboard runs on the same API.
02Regulation, handled
Compliant in the US, in India, and everywhere between.
United States
TCPA, TCR, and 10DLC
The TCPA requires prior express consent for marketing texts, and prior express written consent for autodialed promotional ones. On top of the law, US carriers require 10DLC brand and campaign registration through The Campaign Registry before application-to-person traffic will deliver reliably.
CaviusConnect files your TCR brand and campaign registrations, tracks approval, enforces opt-out keywords like STOP automatically, and checks every send against the recipient's consent record. Read more in our 10DLC registration guide.
India
DLT and TRAI scrubbing
TRAI's DLT regime requires every business texting Indian numbers to register its entity, sender ID headers, and message templates on an operator's DLT platform. Carriers scrub every message against those registrations, and unregistered content is simply dropped.
We run your DLT registration end to end, keep your approved templates in sync so a mismatched send is blocked before the carrier ever sees it, and map DLT consent categories onto the same consent ledger the rest of your channels use. Our DLT registration guide walks through the whole process.
Beyond the US and India, the same engine applies CASL's express-versus-implied consent rules for Canada, GDPR consent standards for the EU, and per-region quiet hours, evaluated on every send in every region you operate in. See the compliance engine for the full framework list.
03The send path
What happens before a text goes out.
Most platforms hand you an API and leave the legal exposure with you. Here, every message answers to the rules engine first. We block, we don't warn.
01
Jurisdiction
The recipient's number is resolved to its regulatory region: TCPA rules for a US number, DLT scrubbing for an Indian one, CASL for Canada.
02
Consent
The consent ledger is checked for a valid opt-in of the right type. Promotional content needs promotional consent; a transactional opt-in doesn't cover it.
03
Quiet hours
Sends are held or blocked outside the recipient's permitted window, using their region's rules rather than your server's timezone.
04
Carrier & template rules
The message is checked against the registered campaign or DLT template it must match. Unregistered content never reaches a carrier.
05
Send, or block with the reason logged
Only messages that pass every check go out. Anything blocked is logged against the contact with the exact rule that failed.
04Developers
