1. Cold Email Infrastructure
Maildoso : Provides complete cold email infrastructure out of the box. You get mailboxes, domains, DNS configuration, and sending capabilities all in one platform. Perfect for teams who want everything set up and ready to go.
Chaleureux : Does not provide email infrastructure. It’s a warmup-only tool that works with your existing email accounts. You need to buy mailboxes separately from Google Workspace, Outlook, or providers like Maildoso.
2. Email Warmup Quality
Maildoso : Includes AI-powered warmup as part of the package. The warmup feature handles basic sender reputation building. It works but isn’t as advanced as dedicated warmup tools.
Chaleureux : Email warmup is Warmy’s core focus. The Adeline AI system is highly sophisticated. It adapts to your sending patterns and builds reputation faster than basic warmup tools.
⚠️ Warning: Warmup alone doesn’t guarantee inbox placement. Your email content, sending patterns, and domain reputation all play important roles.
3. Setup Process
Maildoso : Automates the entire setup process. DNS records including SPF, DKIM, and MX are configured automatically. What usually takes hours of technical work happens in minutes with Maildoso.
Chaleureux : Requires you to have email accounts already set up. You connect your existing Google or Outlook accounts. The setup is simple but assumes you already did the hard infrastructure work.
4. Deliverability Testing
Maildoso : Lacks dedicated deliverability testing tools. You need third-party services to check where your emails land. This is a gap compared to dedicated deliverability platforms.
Chaleureux : Offers powerful deliverability testing. Check inbox placement before launching campaigns. The seed list feature shows exactly where emails land across different providers.
5. Mailbox Management
Maildoso : Excels at managing multiple mailboxes. The master inbox collects replies from all accounts in one place. You can manage 32 to 400 mailboxes from a single dashboard.
Chaleureux : Connects to your existing mailboxes but doesn’t provide inbox management features. You handle replies through your regular email client or other tools like Instantly.
6. Tool Integrations
Maildoso : Integrates smoothly with popular cold email tools. Works directly with Instantly, Smartlead, and similar platforms. Your sending infrastructure connects to your campaign management.
Chaleureux : Focuses on warmup rather than campaign integrations. The main integration is with email providers like Gmail and Outlook. Google Postmaster integration helps monitor Gmail reputation.
7. Gestion des adresses IP
Maildoso : Rotates your emails across multiple IP addresses automatically. This spreads your sending reputation and reduces the risk of getting blocked. Shared IPs mean costs are lower.
Chaleureux : Doesn’t manage IP addresses since it’s a warmup tool. Your IP depends on your email provider. Gmail and Outlook handle the IP infrastructure on their end.
⚠️ Warning: Shared IPs can be risky. If other users on the same IP send spam, your deliverability may suffer. Some providers offer dedicated IPs at higher costs.
8. Language Support
Maildoso : Primarily English-focused for warmup emails. The platform itself works globally but warmup content is limited in language variety.
Chaleureux : Supports over 30 languages for warmup emails. Perfect for international teams sending campaigns in multiple languages. The AI generates natural-sounding warmup content in each language.
9. Domain Protection
Maildoso : Helps protect your main business domain by providing secondary domains for cold outreach. Your primary domain reputation stays safe while you scale campaigns.
Chaleureux : Warms up whatever domains you connect. It doesn’t provide separate domains for protection. You need to set up secondary domains yourself before connecting to Warmy.

Foire aux questions
Qu'est-ce que Maildoso ?
Maildoso is a cold email infrastructure provider that handles your entire email setup. It gives you mailboxes, domains, and automated DNS configuration in one platform. The service handles SPF, DKIM, and DMARC records so you don’t have to. Over 2,000 cold emailers use it to send outreach at scale without dealing with Google Workspace or Microsoft 365. The master inbox feature lets you manage all replies from one dashboard.
Qu'est-ce que Warmy ?
Warmy is an email warmup tool powered by artificial intelligence. It gradually builds your sender reputation by exchanging emails with real accounts in its network. The AI-driven Adeline technology adapts warmup patterns based on your account’s behavior. Warmy also offers deliverability testing through seed lists. You can check inbox placement across Gmail, Outlook, and Yahoo before launching campaigns. The tool supports warmup in over 30 languages for international outreach.
What is cold email infrastructure?
Cold email infrastructure is the technical setup behind sending outreach emails at scale. It includes mailboxes, domains, DNS records (SPF, DKIM, DMARC), and IP addresses. Good infrastructure keeps your emails out of spam folders and into primary inboxes. Without proper infrastructure, even the meilleur email de prospection copy lands in spam. Providers like Maildoso handle this setup automatically so you can focus on writing campaigns.
How does email warmup work?
Email warmup gradually increases your sending volume over 2-4 weeks. The service sends and receives emails automatically from real accounts in a trusted network. This signals to email providers that your account is legitimate. Gmail, Outlook, and Yahoo track sender behavior closely. A new account blasting hundreds of emails immediately looks suspicious. Warmup mimics natural sending patterns to build a positive reputation before you launch cold campaigns.
Is Maildoso good for cold email?
Yes, Maildoso is a solid choice for cold email campaigns if you need infrastructure fast. It automates the technical setup that trips up most beginners. DNS records, domain verification, and mailbox creation happen in minutes instead of hours. The shared IP system works well for most users sending under 10,000 emails per day. High-volume senders might want dedicated IPs from alternatives like Infraforge or Mailscale.
