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.Starting Price: $795 per year -

EtherMail
EtherMail
Legacy Email services use old and obsolete email transfer protocols that resulted in an easy target for hackers to launch cyberattacks through emails. In return of the free email service provided, legacy email providers scan the content of our emails to feed data to their advertising machines. New data privacy laws are designed to address the longstanding issue of unsolicited marketing outreach but will leave room for new advertising paradigms. Anonymous communication between Web3 users and businesses on top of traditional solutions is nearly impossible and is typically circumnavigated with Telegram groups. At the moment, sending/receiving emails between dApp and traditional emails is very challenging. Wallet addresses do not receive automatic alerts from any Web3 activity. -
