One million subscribers. 80,000+ opens from contacts labeled inactive. BioTrust runs email as a primary revenue channel. Their prior ESP was auto-suppressing reachable audience.
BioTrust sells nutrition and supplements to more than one million email subscribers. Email drives revenue at that scale. When their previous ESP started removing contacts its algorithm labeled inactive, sendable audience shrank and the team could not override the logic.
BioTrust moved its full program to Maropost Marketing Cloud, an email marketing software built for list control, ESP migration, and email deliverability at seven-figure scale. Within 30 days, average open rates moved from 15% to 20%, a 33% relative lift on more than one million subscribers.
BioTrust's previous ESP applied a rigid inactivity rule. Contacts the platform classified as inactive were automatically removed from sendable segments. The team could see reach shrinking but could not change the suppression logic when they disagreed with it.
Campaign performance followed audience size down. Shrinking sendable lists and algorithm-driven suppression dragged down results before BioTrust could act.
BioTrust needed a platform that put the brand in control of who receives mail, not one that auto-suppressed reachable contacts. Maropost delivered fresh sending infrastructure and hands-on migration support at seven-figure scale.
One million subscribers. Full authority over list logic. No black-box suppression rules.
Before switching, BioTrust sent a test campaign to subscribers the prior ESP had labeled inactive. Eighty thousand opened. That confirmed the previous platform was cutting off engaged customers, not cleaning dead weight.
BioTrust moved its full email program to Maropost Marketing Cloud, including new sending infrastructure and new IPs. Maropost supported the ESP migration with daily check-ins and off-hours assistance. Campaigns kept moving while deliverability foundations were rebuilt.
On Maropost, BioTrust rebuilt sender reputation on fresh infrastructure with full control over list logic and segmentation. Reporting tracked deliverability from the first sends.
Maropost Marketing Cloud is an email marketing software BioTrust uses for segmentation and campaign execution at one million subscribers.
BioTrust results within the first month on Maropost:
BioTrust is extending the list control and open rate gains from month one across ongoing campaigns. Subscriber experiences, including the custom unsubscribe flow, stay aligned to brand standards. Support response times on chat keep operational questions from slowing sends.
BioTrust's switch shows why high-volume senders choose Maropost Marketing Cloud: list logic they control, deliverability infrastructure they can rebuild on, and hands-on migration support while campaigns keep running. The platform combines unified contact management, segmentation, email and SMS execution, journey automation, and eRFM analytics in one environment. Teams get a robust deliverability mechanism and performance reporting on the same screen they use to build segments and send, so diagnosis and action happen in one place instead of across disconnected tools or black-box suppression rules.
