You create the community

When you are a major brand, like a hotel or healthcare group, you are operating a kind of multi-unit building. Your sub-brands do a lot of work for you, but at the end of the day, you need to have total oversight to succeed and protect all the residents.

But you have to assign your tenants to apartments and get them securely settled. With SocketLabs, adding subaccounts is a fast and easy process. We immediately create a Rule Engine instance and provide them a dedicated IP, and from there, you set their specific parameters. 

You monitor the community

Our account-level dashboard gives you an at-a-glance vision of total performance with subaccount StreamScores (our proprietary reputation signal) that you can sort by several different factors.

Noticing one brand struggling with their StreamScore? You can click into the subaccount to see some Guided Insights; granular detail explaining why this might be, recommendations for resolution, and a sending overview just for that sender. 

Use SocketLabs messaging APIs for all your email sending needs, available in C#, PHP, Node.js, Python, Golang, Java, and Ruby

You protect the community

At the end of the day, you are in charge of every subaccount. Maybe you’ve passed on our tools to each brand’s own email wizards (we have an API for that) or maybe you’re running them all yourself. But your job is to make sure they’re all doing well.


We give you the ability to automate IP routing and segmentation to protect your good senders while less-good senders try to get it together. With Rule Engine, just set your no-code parameters and let it do the work for you. It’s your on-call maintenance manager.

We're made for you

Your use case is really particular and all other ESPs are designed for direct senders. We’re not. We’re designed to support you and your unique needs.


The ability to set up subaccounts quickly and easily while pass on tools via API is key for CRMs.

Our step-by-step authentication instructions keep proper authentication from being a slog.


A perfect example of managing multiple brands and audiences, this use case speaks directly to the power of our platform.

Easily decide which senders belong in which pool with code-free routing to better protect and improve IP pool performance.
