The email warm-up tool built for casino and betting senders. Improve inbox placement, protect sender reputation, and stop losing players to spam folders
No Credit Card Required | Cancel Anytime
Chance your casino bonus email lands in spam
Average open rate in gambling without warm-up
Inbox placement rate for cold gambling domains (vs 91% after warm-up)
Gambling content gets flagged
ISPs scan for casino and betting language, then quietly route campaigns to spam or the promotions tab. Open rates crater with no explanation.
Cold domains burn fast
Blast a fresh domain to 200k players and its reputation is gone in a day. Without warm-up, high volume is a liability, not an advantage.
Affiliate lists drag you down
Player data sourced through affiliates is full of dead addresses and spam traps. One bad send can permanently damage a domain you spent months building – and some never recover.
Warmy sits under whatever CRM or ESP you already use. It doesn’t send your campaigns and it doesn’t care that they’re gambling – it makes sure the inbox trusts your domain when you hit send

Automated, human-like warm-up across Gmail, Outlook, Yahoo, and more builds trust for 2–4 weeks before your first real casino campaign
Before sending to your players, run a placement test. See exactly where your campaign lands across every major provider: inbox, promotions, or spam.
Live reputation, blacklist, and SPF/DKIM/DMARC monitoring alerts you the moment a domain slips – so you fix it before it costs you a campaign

Inbox placement
Emails marked as spam
Illustrative example based on typical lift. Actual results depend on list quality, content, and sending history
Since moving our casino domains onto Warmy, inbox placement on reactivation campaigns jumped from the low-60s to the mid-90s – and we finally stopped burning fresh domains every launch
Gambling content gets extra scrutiny from mailbox providers, and high-volume promo sending on a cold or under-warmed domain trips spam filters almost immediately. The reliable fix is a warmed-up sending domain, correct SPF/DKIM/DMARC, clean lists, and consistent engagement. Warmy automates the warm-up and reputation side so the content isn’t what sinks you.
It’s built for exactly this. Warmy combines automated domain warm-up, inbox placement testing, and live reputation monitoring targeting the specific reasons casino and betting emails land in spam. Because Warmy isn’t an ESP, it supports gambling senders that mainstream marketing tools reject. Casino, sportsbook, and affiliate operators use it for high-volume sending.
Yes. Warmy is a deliverability tool, not an ESP. It never sends your campaigns, so it doesn’t restrict gambling or casino content the way most mainstream platforms do. It warms up and monitors the domains and mailboxes you already own. You send through whatever provider or CRM allows iGaming traffic and Warmy makes sure your domain is trusted when you do.
Plan for 2 to 4 weeks, depending on the daily volume you’re building toward. Warmy ramps sending gradually and adjusts the pace based on how Gmail, Outlook, and others respond. You’re following real signals, not a fixed calendar. Higher target volumes take longer and Warmy sets the schedule automatically.
Run a placement test in Warmy before every major send. You’ll see exactly where your campaign lands across Gmail, Outlook, Yahoo, and more: inbox, promotions, or spam, provider by provider, before a single real player receives it. You can run this test at any point during warm-up or before any campaign goes out.
The promotions tab is a Gmail sorting decision, not a spam verdict. It’s triggered by promotional formatting, bulk-style HTML, image-heavy templates, and low recent engagement. Simpler, more personal-looking bonus emails from a warmed, reputable domain are far more likely to land in the primary inbox. Warmy builds the domain trust and engagement history that pulls you out of promotions.
Email marketing for gambling isn’t the same job as marketing for retail or SaaS. The volume is higher, the content trips more filters, and one careless promo blast can blacklist a domain you spent months building.
Warmy is the layer that handles it — continuous domain warm-up, inbox placement testing, and reputation monitoring that runs on its own, tuned for the sending patterns casino, sportsbook, and affiliate brands actually run.
