How Alchemail Improved Deliverability and Reply Rates with Aerosend

Overview

Alchemail is a cold email agency that helps businesses drive qualified meetings through scalable outreach. Arthur, Founder of Alchemail, has been running cold outreach since 2015, long before AI and automation became mainstream. Over the years, he has experimented with dozens of tools and private SMTP vendors, searching for a platform that could provide both stability and consistent performance for large-scale campaigns.

The Challenge

Before switching to Aerosend, Arthur had tried several private SMTP vendors, along with traditional setups on Google and Microsoft. The problem was that every time he sent from these major platforms, performance was inconsistent. Accounts often got flagged, throttled, or lost reputation, causing deliverability to drop quickly.

The Switch to Aerosend as an Alternative to Google

Arthur first connected with Aerosend through a cold outreach conversation. After reviewing how the platform worked, including its warmup systems, domain infrastructure, and backend processes, he decided to test it.

He onboarded four clients immediately, warmed up the mailboxes for about a month, and began sending low-volume campaigns at around 10 to 20 emails per day. The setup was simple, the process predictable, and the support responsive.

The Results

The results soon justified the switch. For one of his clients, campaigns run through Aerosend consistently outperformed those using Google-based setups. When sending to Google domains from Aerosend, the team achieved one positive reply for every 25 contacts, a conversion rate nearly three times higher than Google-to-Google sends.

Alchemail got 20 to 40 meetings per month for a single client. As performance stabilized, Alchemail scaled up its infrastructure and began adding more Aerosend accounts for new projects.

“My experience with Aerosend has been overwhelmingly positive. The support is excellent, the results are repeatable, and the system just works. We’ve run campaigns that perform as well as, or even better than, Google. It’s rare to find a platform that delivers at this scale and still backs you up when things go wrong.” – Arthur, Founder, Alchemail
