Protecting Your Deliverability With Honeypots

Dunno about you, but I find it oddly satisfying every time I flag a spammer and stop them in their tracks. It’s like I’m tag-teaming with ISPs to police the interwebz, fighting the good ol’ fight. And there’s a lot that ISPs can learn from in-house efforts to stop spammers, especially from traps like honeypots that are meant to ban spammers from your email servers. Honeypots are a sticky topic (pun intended) because there’s a lot of upside to using them. That’s good news for you, but bad news for the unsuspecting target.

Mailgun Launches Automated IP Warm Up Service

Today, we’re happy to share that there’s a new, automated way to prepare your dedicated IPs to send email through Mailgun. If you’ve ever had to warm up an IP manually, you know how much it sucks: prep then send specific volumes of email every hour and increase the volume thereafter. You’re an F-Zero pilot, constantly challenging your reflexes – and sweating bullets in the process – because you can hit the brake too late and go overboard. It’s a pain, and it’s also really easy to screw up.

Avoiding The Blind Spots Of Missing Data With Machine Learning

You have a project, and you want to apply machine learning to it. You start simple: add one feature, collect data, create a model. You add another feature that’s really useful, but it’s only represented in half of your data points. You want to be smart and use all the data you have (including the one with missing values), but how do you do that?
