OptInFix

OptInFix is a specialized platform for collecting and managing compliant SMS opt-ins. It solves a critical gap in SMS marketing where businesses fail to meet regulatory and carrier requirements due to inconsistent or undocumented consent collection. The platform enables companies to deploy embeddable consent forms across websites, landing pages, and funnels, ensuring every opt-in is captured with proper disclosures and verifiable records. Each submission is logged with timestamps and user details, creating a structured audit trail that supports both 10DLC campaign approvals and TCPA compliance. OptInFix is built for businesses and agencies that need a reliable, repeatable way to collect consent without risking campaign rejection or legal exposure. It converts fragmented, manual consent processes into a standardized system that is defensible, scalable, and aligned with compliance requirements.

Prodocom

Prodocom is a Certified Australian Owned business communications company, founded in Sydney in 1997. For almost three decades it has provided bulk SMS, email marketing, MMS, voice broadcasting and online fax services to more than 4,000 Australian businesses and government organisations, from healthcare providers and councils to logistics companies, financial services firms, associations and marketing agencies. Prodocom's platform combines every channel in one login. Businesses can send a single message or run large-scale, automated campaigns across SMS, email, voice and fax, and move contacts through multi-stage sales funnels that trigger the right message on the right channel based on customer actions. For SMS, Prodocom works as a full SMS gateway: two-way messaging, personalised texts, business-name sender IDs, dedicated numbers and short codes, keyword campaigns, auto-replies, automatic STOP opt-outs, link tracking, delivery reports and text-to-landline. An AI writing assistant helps teams draft and refine messages. MMS supports images, GIFs, video and audio, with two-way replies. The email marketing tools include a drag-and-drop HTML builder, ready-made templates, HTML import, A/B testing, automated email sequences, personalisation, attachments and sending from a custom domain with SPF and DKIM authentication. Built-in deliverability checks review templates and contact lists before sending, and reports track opens and clicks. Voice broadcasting sends text-to-speech or recorded messages to mobiles and landlines, with keypad responses, voicemail delivery and call reporting. Online fax replaces the fax machine with email-to-fax, fax-to-email, fax broadcasting, automatic cover pages and dedicated or ported fax numbers, supporting the fax workflows still common in healthcare, legal and government. Prodocom also delivers invoices, statements and other documents through a secure portal with online payment. The platform includes a built-in CRM and connects with over 200 major CRMs and business systems, including Salesforce, HubSpot, Microsoft Dynamics 365, Zoho, Xero and MYOB, with webhooks for real-time updates. Where an integration doesn't exist, Prodocom's in-house developers build custom API integrations. Security and data sovereignty are central to the service. All data is stored onshore on Prodocom's own infrastructure in NEXTDC's Sydney data centre, and the platform is IBM-audited, independently penetration-tested, and supports two-factor authentication, user permissions and sub-accounts. Prodocom is registered with AFCA. Customers can run campaigns themselves or use Prodocom's professional services team to design, build and send them, with in-house Sydney-based support available 24/7. Pricing is pay as you go: customers pay only for messages successfully delivered, with no lock-in contracts or setup fees, and the first send is free.

Tekservix

Tekservix is a business messaging and mobile app platform for companies of every size, worldwide. It brings WhatsApp messaging, SMS, an AI sales agent and iOS and Android app building into one account, so a business does not need a separate vendor for each channel. WApenda is the WhatsApp API gateway. A company links its own number by scanning a QR code, with no Meta approval needed, then sends messages, images, documents and campaigns from a dashboard or a REST API. Replies arrive by webhook, and keyword auto-replies can answer common questions at any hour. SMS Gora turns Android phones into an SMS gateway. Businesses send and receive SMS from their own phone and SIM card through a REST API, with bulk campaigns, CSV upload, auto-replies, an inbox and webhooks for incoming messages. There is no carrier contract or sender approval. The AI Sales Agent learns a company's products from its website, answers customers on WhatsApp and SMS, recommends the right product, shares how to pay and passes conversations to a person when needed. WApenda and SMS Gora are included in every plan. For mobile, Tekservix offers three routes. App Studio turns a website into iOS and Android apps for a one-time price, and the app stays in sync with the site. The Native App Builder creates true native iOS and Android apps from a dashboard, with features such as Face ID, in-app purchases and offline mode. Companies that need something more specific can have the Tekservix team build a custom app at a fixed price. Every route leads to the App Store and Google Play, and Tekservix can handle publishing. Tekservix also includes AI writing and image tools, PDF tools, invoices, SEO tools and a social media scheduler. Teams can start with the free tools, try WApenda and SMS Gora for three days without a card, and test an Android app for seven days. Payment is by card, wallet or crypto.
