About
Alex Rosca runs SendHaven, a dedicated email infrastructure provider for the businesses mainstream ESPs refuse: iGaming and online casinos, crypto, forex, CBD and nutra, adult, dating and cold email. Before SendHaven he spent years on the media-buying and affiliate side of iGaming, where email and SMS were the channels that produced depositors, and where getting suspended by a shared ESP mid-campaign was a monthly event. SendHaven exists because the fix for that problem, dedicated servers with aged domains, proper authentication and a managed warm-up, was something every operator had to rebuild themselves.
He writes here about what actually decides inbox placement for high-risk senders: IP and domain reputation, warm-up schedules, authentication, list quality, and which providers will or will not take your category. The comparisons on this site name competitors and their prices, and say where they are the better choice, because a reader who is sent to the wrong provider does not come back.
