Inbox Zapper vs. Opt-Inbox Comparison Chart

Sendio’s Opt-Inbox is a proprietary sender management process, acting on messages having cleared email security, which would otherwise be released into a user’s inbox, ensuring that recipients only receive messages from desirable sources, whether from individuals or subscriptions, leaving the new yet undecided sources to the recipient’s discretion in a queue separate from the usually messy quarantine queue. Despite being protected by advanced email security systems, many inboxes continue to be inundated with countless security-cleared messages comprised of persistent sales pitches and marketing communications, distribution lists and bulk sources. Separating harmful messages in the quarantine queue from nuisance and potentially desired ones is increasingly difficult. This can become particularly troublesome for executives and professionals who can’t afford to overlook an important email and find out later they had a desirable message (false positive) in their cluttered quarantine queue.
