Before you send, clean your list. We partner with EmailListVerify to help you clean your list before sending — removing invalid, disposable, and risky addresses that destroy 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, dating apps, 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 the 3-Server, 5-Server, and Custom 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 3-Server, 5-Server, and Custom 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.
Mainstream email service providers enforce acceptable-use policies that exclude entire industries. SendHaven was built specifically for those businesses.
Deposit confirmations, withdrawal receipts, bonus campaigns, and player-retention sequences are mission-critical for any online casino operator. Mainstream ESPs treat iGaming as a prohibited category, leaving operators without reliable email infrastructure — SendHaven fills that gap with dedicated servers purpose-built for the iGaming vertical.
Token launches, exchange alerts, wallet notifications, and 2FA emails demand flawless deliverability — a missed security email is a support ticket or a lost user. Mailchimp, SendGrid, and Brevo have all published policies that explicitly ban cryptocurrency businesses. SendHaven provides email infrastructure for crypto with no questions asked, provided your operation is legitimate.
Trade confirmations, margin-call alerts, and market-update newsletters are regulatory requirements for licensed forex brokers, yet shared ESPs routinely suspend CFD and forex accounts on sight. SendHaven is the best ESP for forex operations that need consistent delivery without the constant risk of account termination.
Product-launch campaigns, subscription renewal emails, and promotional newsletters for CBD and nutraceutical brands are refused by mainstream providers regardless of legal status. SendHaven gives CBD operators a dedicated email server with no category restrictions, so your campaigns reach inboxes on day one.
Age-verified audiences, content-release alerts, and subscription management emails for adult platforms are met with zero tolerance by mainstream email providers. SendHaven operates with a high-risk email sender mindset — your legal, consented audience deserves reliable delivery through dedicated infrastructure that won't disappear overnight.
Match notifications, profile-activity alerts, and subscription reminders for dating apps and platforms are flagged as spam by shared ESPs the moment volume spikes. SendHaven gives dating operators isolated sending infrastructure so verification emails, match alerts, and renewal notices actually hit the inbox instead of promotions or spam.
High-volume B2B outreach campaigns obliterate shared IP reputation within days, triggering suspensions and blacklists that hurt every other sender on the pool. A dedicated email server for cold email gives your outreach team isolated sending infrastructure, domain rotation, and clean IP addresses that don't carry the sins of other senders.
If you've been rejected by SendGrid, Mailchimp, Brevo, or any other mainstream ESP because of your industry, SendHaven provides dedicated email infrastructure with no acceptable use restrictions for licensed and legitimate high-risk businesses. We work with iGaming operators, crypto exchanges, forex brokers, CBD brands, adult platforms, dating apps, and cold-email agencies — the businesses that every other provider turns away.
Shared sending pools trade convenience for control. When your business depends on email, that trade-off is unacceptable.
A dedicated email server gives a high-risk sender complete ownership of their sending reputation. Unlike shared platforms where a single bad actor can collapse email deliverability for hundreds of unrelated businesses, dedicated email infrastructure means that every decision affecting your sender score is your own. SendHaven provisions dedicated IP addresses and fully configured servers so that iGaming operators, crypto exchanges, and forex brokers can build a genuine sender reputation over time, not one borrowed from a shared pool they have no visibility into.
For businesses evaluating a SendGrid alternative that actually supports high-risk verticals, dedicated email infrastructure is the only architecture that makes sense at scale. Shared ESPs are optimised for low-risk SaaS companies sending newsletters — they were never designed to handle the volume, content, or compliance requirements of regulated industries. SendHaven's dedicated SMTP servers are built from the ground up for exactly those use cases, providing the email deliverability, stability, and operational continuity that high-risk senders demand.
