Stable and Scalable Cold Email Infrastructure
For years we’ve run a cold email outbound agency known for exceptional cold email sendability and deliverability.
If you need to send cold email with stability and scalability while avoiding domain damage, spam filtering, and sending limitations – we figured out how.
What Is Senders Protocol?
Senders Protocol is a proprietary mix of in-house and off-the-shelf tools, IP addresses, subdomain and DNS Configurations, testing patterns, and intervention procedures. It is called a “protocol” because it isn’t a ‘single turnkey thing’ but rather a set of things that make it work – it is a service that we do for you.
What Is Senders Protocol Used For?
Senders Protocol is for sales and partnership teams who are cold emailing their prospects and feel limited in sending volume, worried they are getting spam flagged, or need to safely scale up cold email while avoiding domain or reputational damage.

No. Senders Protocol can work with almost any tools you are already using - Apollo.io, Outreach.io, Salesloft, Hubspot, etc. and your sales folks will not need to check a separate inbox to retrieve their email replies.
