The Leading Partner in Email Deliverability Services

Avoid Sending Disasters

Sending outbound emails on your own can end in disaster. Don’t leave your email delivery to chance! From getting lost in the spam folder to sending duplicate messages to your contact list, there are many opportunities for email deliverability to go wrong. With SocketLabs email delivery services, you can rest assured that your emails will be delivered safely and reliably.

Apply Best Practices

Our proven strategies help you avoid the spam folder and improve email delivery. For example, most ISPs block you from sending more than a certain number of emails. But we’ve engineered our software and email delivery system with special ISP (Internet Service Provider)-specific traffic-shaping algorithms that contour email delivery uniquely for each ISP — such as Yahoo!, Hotmail, AOL, and other corporate domains. Our email delivery systems analyze and process responses from these ISPs in real time and adjust email delivery accordingly.

Turn up the Volume

Open source and custom built SMTP servers are not designed to effectively deliver bulk outbound email. Bulk email is delivered in batches that create spikes in the email delivery pattern. These spikes raise red flags with receiving ISPs and can cause messages from traditional servers to be quickly blocked. SocketLabs employs multiple processes including sender authentication, ISP relationship management, and encouraging whitelist subscriptions to ensure maximum email deliverability.

Trusted By:

We developed a mass email delivery system in-house, and when we started to overwhelm our servers, we turned to SocketLabs' dedicated outbound email solution. The SocketLabs email servers are not only fast, but they are extremely reliable. Our franchise community couldn't be happier!
