CompleteSMS is a business-SMS platform designed to let companies send and receive text messages from their desktop, mobile device, email, or web browser, without needing a developer. It supports both one-to-one and bulk SMS sends, with full two-way messaging; you can send messages from your browser, email (Gmail or Outlook), spreadsheet, or via API, and recipients’ replies come back into your inbox just like normal messages. CompleteSMS handles contact management (unlimited contacts & lists), message templates, long-text support (up to 765 characters), dedicated local-area numbers (“long codes”), message threading, scheduled sends, and automatic opt-out/blacklist compliance (e.g., handling “STOP” replies). It also offers features like call-forwarding (so customers who call your SMS number are routed to a voice-enabled device), detailed user/usage reporting, delivery & error reports, and support for compliance with regulations such as US 10DLC or country-specific sender-ID rules.

It also includes automatic list-cleaning to remove invalid or undeliverable numbers, reducing waste on dead contacts. It provides real-time analytics at the carrier level, so you can see which messages were delivered or failed (including error codes), giving you greater visibility into campaign performance.
