USE CASE / IGAMING
Gambling is the vertical mainstream ESPs reject the fastest — not over deliverability, but over their own payment processors and legal exposure. If you’re a licensed operator mailing players in jurisdictions where you’re authorized, you need infrastructure that will actually take you.
01 / THE PROBLEM
Online gambling is associated with chargebacks, cross-border legal complexity, and heavy regulation, so ESPs find it cheaper to prohibit the entire category than to evaluate licensing state by state. SendGrid and most competitors list gambling as restricted or banned outright — an authorized New Jersey or Pennsylvania operator gets the same rejection as an unlicensed offshore book.
That leaves licensed operators with real player CRM — welcome offers, deposit bonuses, retention, responsible-gaming notices — and nowhere compliant to send it. Player mail is also time-sensitive and high-volume, so shared-pool throttling and sudden suspensions are especially damaging around promotions and events.
We route player mail to Gmail on dedicated, warmed infrastructure, monitored daily, so you can run retention and promotional programs at volume with reputation you control — within the jurisdictions and licensing you operate under.
02 / THE GAP
03 / THE STACK
The same dedicated, managed infrastructure across every account. The vertical changes what we watch for; it does not change the guarantees.
Customer traffic is routed exclusively to @gmail.com and enforced at the mail server, so your reputation is built where your list actually is.
One dedicated IPv4 paired with one dedicated sending domain per slot, provisioned to your account and never shared with another tenant.
50,000 to 100,000 content-matched warmup messages per domain per day through Google-operated infrastructure, continuously managed.
Every sending domain synced daily to Google Postmaster Tools; domain and IP reputation, spam rate, and authentication tracked and remediated.
RFC 8058 one-click unsubscribe on every send, with bounces and complaints propagated to a per-customer suppression list automatically.
SMTP responses, deferrals, and complaint trends drive automatic throttling and human triage before a reputation problem becomes an outage.
04 / COMPLIANCE
iGaming acceptance is conditional on documented licensing for the jurisdictions you mail into. US online gambling is regulated state by state (New Jersey, Pennsylvania, Michigan, and others), layered over federal law including UIGEA, with requirements around age verification (21+ in most states), geo-restriction, self-exclusion honoring, and responsible-gaming disclosures. Mailing players in a jurisdiction where you are not licensed to accept play is a categorical refusal in our AUP.
You own licensing, geo-targeting, and self-exclusion list management; we require evidence of licensing before provisioning, and we enforce suppression so exclusion and opt-out requests take effect immediately. This is infrastructure for compliant operators — not a route around the regulator.
05 / FAQ
Yes — licensed operators, with documented evidence of licensing for the jurisdictions you mail into. That evidence is a provisioning requirement, not a formality. Mailing players where you are not authorized to accept play is a categorical refusal under our AUP.
Because their payment processors, banks, and legal teams treat gambling as high-risk, and a blanket ban is cheaper than evaluating each operator’s licensing. It is a business and compliance decision on their side, not a statement about your mail — which is why dedicated infrastructure that will actually take licensed operators solves it.
Yes, to players in jurisdictions where you’re licensed and to recipients who’ve consented, with the responsible-gaming and self-exclusion handling your license requires. The stack is built for exactly this high-volume, time-sensitive player CRM — warmup and throttling are sized so a big promotional send doesn’t cost you the domain.
Suppression is enforced at the infrastructure layer: opt-outs via one-click unsubscribe and any addresses you add to your suppression list stop receiving mail immediately. You remain responsible for maintaining self-exclusion lists per your license; we ensure the send side honors them without delay.
No. Acceptance is conditional on licensing evidence for the jurisdictions you mail. Unlicensed gambling into restricted jurisdictions is a categorical refusal. We serve compliant operators who need infrastructure the mainstream market won’t give them — not operators trying to route around regulation.
