Gmail has aggressive spam filtering 🚧
New email servers aren’t discovered 🔍
Result: Emails end up in spam 💀
Gmail's spam filters mislabel self-hosted server emails, causing delays.
This disrupts time-sensitive, critical communications 🕰️
Existing spam protection 🚧
Google is known to be using a combination of technologies to detect spam emails, including machine learning algorithms trained on several patterns, blacklists and whitelists, sender reputation (based on previous spam complaints, bounce rates, and sending-domain age), authentication protocols like SPF, DKIM, and DMARC (to verify messages being sent from authorized senders tamper-free, helping phishing and spoofing attacks although spammers can get around this), user remarks, and rate-limiting (enforced on newer email servers with a lower reputation to prevent large-scale spamming).
Independent email servers suffer 😢
Anyone could decide to use their own email servers or set up services to do it for customization and control, specific privacy measures, business data protection in communication, regulatory compliance, reducing reliance on third-party providers, or just plain experimentation. In any case, aside from the maintenance challenges, potential issues with email deliverability might just be fighting a losing battle.
Can Google do something? ✳️
Although email is an open protocol across providers, including giants like Google, Yahoo, Microsoft, Proton’s ProtonMail, etc., there could be some potential actions that could allow better email sending rates + enhanced sender reputation for newly-hosted servers or domains like domain verification (with business / ID documentation), feedback loops with receivers & senders, whitelist programs.
I personally use Purelymail for my custom emails.
$10 a year with no hard limits on users, domains, storage.
No deliverability issues yet.
Perfect for my use case ✨
That’s all folks! ✌🏼
