Flowmailer, now operating as Spotler SendPro, functions as a specialized email delivery platform focusing on transactional emails for a diverse client base that includes service providers, webshops, and insurance companies. The company was founded in 2014 by Richard van Looijen and is headquartered in Rotterdam, Netherlands. Its creation was a direct response to customer demand from within the email marketing software MailPlus (now Spotler) for a more dedicated and reliable platform for transactional email delivery.
The company's core business is providing a high-performance infrastructure for sending high-volume transactional emails, such as order confirmations and invoices, ensuring they reach the recipient's inbox. This is achieved through a robust SMTP relay service and a comprehensive REST API, allowing integration with various source systems like CRMs and CDPs. Flowmailer's business model is subscription-based, with pricing tiers determined by the monthly volume of emails sent. In March 2020, Flowmailer was acquired by the Spotler Group, a European marketing technology company, to complement its product portfolio with specialized transactional email capabilities. As part of the Spotler brand, the platform was renamed Spotler SendPro, and its founder, Richard van Looijen, took on the role of R&D Director within the new organization.
The platform offers a suite of features designed to maximize email deliverability and provide developers with extensive control. Key functionalities include advanced templates, real-time analytics, DMARC reporting, and dynamic PDF attachments. It operates on a self-hosted infrastructure with redundant data centers in the EU, ensuring compliance with GDPR and ISO 27001 certification. The service is designed for technical users and allows for detailed tracking of email events through webhooks, open and click tracking, and management of bounces and message archives. Initially focused on the Dutch market with clients like VodafoneZiggo and Eneco, the company has expanded to serve international brands such as Asics.
