Case Study: GuideSpark achieves a drop in bounce rates from 20% to 2% with Informatica Email Verification Plus Hygiene

GuideSpark Relies On Email Verification Plus Hygiene To Better Manage The Explosive Growth In Its Growing Email Address Database

GuideSpark, a SaaS communications platform that helps employers deliver benefits and onboarding content, faced explosive email database growth — from 10,000 to 400,000 addresses (a 3,900% increase) in 18 months. The company needed to monitor database health, avoid spam traps and hard/soft bounces, integrate verification into its Marketo workflow via webhooks, and maintain at least 98% deliverability while classifying addresses as valid, invalid, or malicious.

Using Informatica’s Email Verification Plus Hygiene (Data as a Service) integrated into Marketo, GuideSpark automated pre-send verification, segmented and labeled addresses by status and activity, and produced instant executive reports. The solution improved database management, removed irrelevant addresses, and cut bounce rates from 20% to 2%, substantially reducing risk to sender reputation and improving deliverability.
