You can now request a demo from our website. I'm personally meeting with every single new customer to truly understand your needs so we can continue building the best cold email solution for agencies & B2B companies.
Over the past few years, platforms like Smartlead.ai, Instantly.ai, and my own product Uptics.io have made cold emailing more accessible than ever.
This wave of user-friendly tools has allowed countless agencies to jump headfirst into cold email, dramatically expanding the volume of emails hitting inboxes each day.
While these all-in-one solutions have certainly lowered the barrier to entry, they’ve also created a new deliverability conundrum: the more mainstream cold email becomes, the easier it is for Google, Microsoft, and other major email providers to detect (and penalize) suspicious sending patterns.
That’s because many popular platforms rely on a network of shared IPs and proxies, distributing client messages across a common infrastructure.
In this newsletter, I’m going to explain the difference between Proxy & Dedicated Servers/IPs and how it impacts email deliverability, which is the cornerstone of success with cold email.
And when it comes to your agency, hitting the primary inbox is the single most crucial factor for your success.
