Silverpop
Atlanta-based marketing automation and email marketing company acquired by IBM in 2014.
Last updated August 24, 2026
Overview
Silverpop was an Atlanta-based cloud software company focused on marketing automation and email marketing. It served both business-to-business and business-to-consumer marketers with tools for creating, scheduling, segmenting, and measuring digital campaigns. Its platform also supported lead nurturing, behavioural tracking, and automated communications triggered by activity across email and web channels. The business began in 1999 under the name Avienda Technologies, co-founded by Aaron Shapiro and David Bloom. During its first two years, it raised approximately $35 million from Draper Fisher Jurvetson and Gray Ventures and appointed Bill Nussey as chief executive officer. The company subsequently adopted the Silverpop name and broadened its proposition beyond email delivery. Rather than operating solely as an outbound email service, it developed a wider marketing-automation platform intended to help mid-market and enterprise organizations coordinate communications around customer and prospect behaviour. Silverpop's principal offering, Silverpop Engage, combined email campaign management with contact segmentation, behavioural monitoring, and workflow automation. Marketers could use activity data—such as interactions with messages or websites—to organize audiences and trigger more personalized communications. This made the platform relevant to demand generation, lead nurturing, customer engagement, and lifecycle marketing programs. The company continued to raise capital as it expanded. In April 2013, it secured a further $25 million from Escalate Capital Partners and Silicon Valley Bank. In March 2014, IBM announced an agreement to acquire Silverpop in a transaction reported at approximately $275 million. Following completion of the acquisition, IBM incorporated Silverpop's technology and capabilities into its marketing software portfolio, including IBM Marketing Cloud. The Silverpop identity was therefore no longer developed as an independent operating brand. IBM later reorganized and rebranded elements of this marketing portfolio under the IBM Watson Marketing name. Silverpop's significance was its combination of email execution and broader behavioural marketing automation at a time when organizations were consolidating campaign, prospect, and customer data into unified cloud platforms. Its acquisition gave IBM an established marketing-automation product and specialized capabilities for personalized, event-driven engagement. The independent Silverpop company is now defunct as a standalone brand, with its technology absorbed into IBM's marketing software activities.
History
Silverpop originated in 1999 as Avienda Technologies, a company co-founded by Aaron Shapiro and David Bloom in Atlanta, Georgia. The business entered the market as cloud-based marketing technology was emerging as an alternative to installed campaign-management systems and basic outsourced email delivery. During 1999 and 2000, Avienda raised approximately $35 million from Draper Fisher Jurvetson and Gray Ventures. Bill Nussey was appointed chief executive officer during this early period. The company later changed its name to Silverpop and expanded its commercial focus. Its proposition moved beyond the technical delivery of email messages toward a broader marketing automation system for mid-market and enterprise customers. The platform was designed for both business-to-business and business-to-consumer use cases, supporting campaign creation, message scheduling, contact segmentation, lead nurturing, and measurement of engagement. Behavioural data from websites and email interactions could be used to classify contacts and initiate automated communications. Silverpop Engage became the company's principal platform. It enabled marketers to build campaigns and workflows, organize audiences according to customer or prospect attributes, and send messages in response to observed activity. This placed Silverpop within the growing category of marketing automation providers that sought to connect email execution with prospect management and personalized customer journeys. Its software was applicable to demand generation, sales-support programs, customer retention, and other lifecycle-marketing activities. In April 2013, Silverpop raised a further $25 million from Escalate Capital Partners and Silicon Valley Bank. The financing supported the company's continued development and expansion as marketing departments increasingly sought integrated cloud tools for digital engagement. By this point, Silverpop had established itself as a specialist provider serving organizations that wanted more behavioural intelligence and workflow control than a conventional email service could provide. IBM announced in March 2014 that it would acquire Silverpop. The transaction was reported at approximately $275 million. The acquisition gave IBM a marketing automation product with established email, segmentation, tracking, and workflow capabilities. It also complemented IBM's broader efforts to build a cloud-based marketing portfolio for enterprise customers. After the acquisition, Silverpop's technology was integrated into IBM Marketing Cloud rather than continuing as an independent company. IBM subsequently used the IBM Watson Marketing name for related parts of its marketing software portfolio. As a result, Silverpop is best understood today as a discontinued standalone corporate brand whose products and capabilities were absorbed into IBM's marketing software operations.
