		Related Products InboxAlly We engage with your emails to teach inbox providers not to send your emails to spam. Our clients have seen their open rates more than DOUBLE within 1-2 weeks! Highly engaged recipients not only open emails, but scroll down as they read. So long as the content is longer than the page, this should be done for nearly all opened emails. When a recipient goes out of their way to take an email out of spam, they are telling the inbox provider, hey, you made a mistake. Moving an email from the promotions folder to the primary inbox tells inbox providers that you disagree with their sorting criteria and it and similar emails should go to the primary inbox. Demonstrates that recipient is interested in the content of your email. We have a set of random generic replies we use for this. Marking an email as important can essentially be interpreted by the inbox provider as "This email is extremely valuable, never send it to spam." 128 Ratings Visit Website Notifii Track Notifii Track is a cloud-based package tracking software for apartment offices, university mailrooms, and corporate mailrooms.

About 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.
