SMS Manager by BulkSMS.com.au

SMS Manager is a web-based bulk SMS and MMS messaging platform for sending single or mass text messages to mobile phones from a browser, with no software to install. It handles day-to-day business communications with staff and clients as well as SMS marketing campaigns, contact and group management, message scheduling, delivery tracking, two-way SMS with replies viewable on the web or forwarded to email, message personalisation, long concatenated messages up to 765 characters, and an API for integration. An AI Writing Assistant drafts and polishes messages on the Send page, and Claude and ChatGPT can be connected under user-controlled permissions to check replies and send on behalf. MMS supports images, and a custom alphanumeric Sender ID can be registered with the ACMA. Multi-user subaccounts, message history exportable to Excel, and delivery tracking are included.

It is aimed at Australian businesses, government agencies, healthcare, education, e-commerce, and nonprofits. Accounts are free to create with a no-obligation free trial and no credit card required; sending is pay-as-you-go through purchased SMS credits with no contracts, setup fees, or monthly fees, and credits do not expire. Volume tiers reduce the per-message rate, with custom pricing available for high-volume sending, and two-way replies cost half a credit per message.
