Before you send, clean your list. We use the EmailListVerify API to validate every address — removing invalid, disposable, and risky emails that destroy your deliverability. A clean list means better inbox placement and a healthier sender reputation from day one.
See what our clients say about their experience with SendHaven.
"After getting banned by SendGrid three times, SendHaven was a lifesaver. Our iGaming platform now sends 200k emails/month without a single issue."
"The 10/10 mail-tester score was a game changer for our crypto exchange. Open rates jumped 40% in the first month."
"We were desperate after Mailchimp shut us down. SendHaven got us back to sending within 48 hours. The infrastructure is rock solid."
Everything you need to know before getting started.
We support iGaming, online casinos, crypto exchanges, forex brokers, CBD/nutra brands, adult content platforms, and cold email senders. Essentially any business that mainstream ESPs refuse to serve.
SendGrid and Mailchimp have strict acceptable use policies that ban high-risk industries. SendHaven provides dedicated infrastructure with no shared reputation, full authentication, and no restrictions on industry type.
Our infrastructure consistently achieves 10/10 on mail-tester.com and above 90 on Google Postmaster Tools. We achieve this through proper authentication, IP warmup, and ongoing monitoring.
Yes, warmup service is included in Growth and Agency plans. We gradually increase sending volume over 4–6 weeks to establish strong sender reputation with major inbox providers.
Absolutely. You bring your domains, we configure SPF, DKIM, DMARC, and ARC records. Custom tracking domains are available on Growth and Agency plans.
We proactively monitor domain and IP reputation. If a domain shows signs of blocklisting, we immediately rotate to backup domains and work on remediation. Multi-server rotation minimizes single points of failure.
