But that&#8217;s not what this is really about.<\/p>\n<p>Warm-up alone won&#8217;t solve misconfigured DNS records, a prospect list full of invalid addresses, or overly commercial content. <strong>If your deliverability is catastrophic, Warmy can help, but it&#8217;s no substitute for a thorough audit<\/strong>. What really sets Warmy apart from its competitors is that it understands this. Behind the warm-up tool lies a complete infrastructure for monitoring email deliverability: blacklists, domain reputation, DNS analysis, performance by provider&#8230;<\/p>\n<p>This makes Warmy.io one of the most advanced tools in its category. But, on the downside, it&#8217;s also the most expensive&#8230;with an opaque pricing model that can quickly become prohibitively expensive if you don&#8217;t know exactly why you need it.

deliverability infrastructure on the market. Its Adeline AI, semantic heating by sector and continuous monitoring make it a tool with no direct equivalent. The major drawback: a per-inbox pricing model that can quickly sting, and deliberately opaque rates.<\/td>\n<\/tr>\n<tr class=\"text-sm font-light\">\n<td class=\"p-2 border border-slate-600\"><strong>Warm-up efficiency<\/strong><\/td>\n<td class=\"p-2 border border-slate-600\">4,7 \/ 5<\/td>\n<td class=\"p-2 border border-slate-600\">Real mailbox network, adaptive AI, semantic heating by industry: the results are there and the gains in terms of open rates are real (around 20%). It&#8217;s a really powerful tool on Gmail \/ Google Workspace, a little less so on Outlook.<\/td>\n<\/tr>\n<tr class=\"text-sm font-light\">\n<td class=\"p-2 border border-slate-600\"><strong>Functional depth<\/strong><\/td>\n<td class=\"p-2 border border-slate-600\">4,6 \/ 5<\/td>\n<td class=\"p-2 border border-slate-600\">It&#8217;s far beyond a simple warm-up, and that&#8217;s a very good thing. Warmy is really an all-in-one email health platform.<\/td>\n<\/tr>\n<tr class=\"text-sm font-light\">\n<td class=\"p-2 border border-slate-600\"><strong>Quality-price ratio<\/strong><\/td>\n<td class=\"p-2 border border-slate-600\">3,5 \/ 5<\/td>\n<td class=\"p-2 border border-slate-600\">The technology is worth the price, but the per-inbox model penalizes growth. Beyond 5-6 mailboxes, the bill explodes. Competitors offering unlimited inbox plans (TrulyInbox, Mailivery) are 3 to 5x cheaper for scalable teams.<\/td>\n<\/tr>\n<tr class=\"text-sm font-light\">\n<td class=\"p-2 border border-slate-600\"><strong>Easy to handle<\/strong><\/td>\n<td class=\"p-2 border border-slate-600\">4,2 \/ 5<\/td>\n<td class=\"p-2 border border-slate-600\">Setup in less than 25 seconds, according to Warmy (in real life, count on a little more than that!). Once the boxes are connected, the system runs autonomously. On the other hand, the profusion of dashboards and parameters can be intimidating for non-technical users.<\/td>\n<\/tr>\n<tr class=\"text-sm font-light\">\n<td class=\"p-2 border border-slate-600\"><strong>Customer support<\/strong><\/td>\n<td class=\"p-2 border border-slate-600\">4,6 \/ 5<\/td>\n<td class=\"p-2 border border-slate-600\">One of our unanimously recognized strengths.

The story of its creation is fairly representative of a certain type of SaaS tool: Shnaider ran several companies, one of which relied heavily on <a href=\"https:\/\/salesdorado.com\/en\/outbound-sales\/b2b-prospecting-emails\/\">cold email<\/a> to acquire customers.<\/p>\n<p>Its teams came up against a deliverability wall (opening rates plummeting, emails falling into spam traps). The software solution developed in-house to solve the problem was finally commercialized: Warmy.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-67427\" src=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-scaled.png\" alt=\"\" width=\"2048\" height=\"1059\" srcset=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-scaled.png 2048w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-300x155.png 300w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-1024x529.png 1024w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-768x397.png 768w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-page-accueil-1536x794.png 1536w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><\/p>\n<p>Today, Warmy.io boasts over 35,000 customers and 650,000 domains whose deliverability has been improved. The tool belongs to AnyBiz LTD, which also publishes AnyBiz.io, an outbound IA prospecting platform (see our <a href=\"https:\/\/salesdorado.com\/en\/lead-generation\/review-anybiz-io\/\">full review of AnyBiz.io<\/a>). The relationship between the two products is symbiotic: AnyBiz generates the campaigns, Warmy ensures that the emails reach their destination. This is quite a clever vertical integration in the SalesTech market.<\/p>\n<div class=\"blocTips primary-light\"><i class=\"fa fa-lightbulb-o\"><\/i><br \/>\n<span class=\"title is-5\"><span class=\"title is-5\">Salesdorado&#8217;s opinion<\/span><\/span>Warmy.io is not an outreach tool, and it&#8217;s important to make this clear from the outset. It doesn&#8217;t replace Lemlist, Instantly or The Growth Machine. It only takes care of the reputation of your domains and your sending infrastructure. For effective <a href=\"https:\/\/salesdorado.com\/en\/cold-email\/\">email prospecting<\/a> campaigns, the two are complementary but distinct.\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"warmyios-key-features\"><\/span>Warmy.io&#8217;s key features<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"adeline-ai-the-warm-up-engine\"><\/span>Adeline AI: the warm-up engine<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>The classic email warm-up is based on a simple logic: send progressively more and more emails to &#8220;accustom&#8221; suppliers to your domain<\/strong>. The problem is that Google and Microsoft algorithms have learned to recognize these regular, predictable increments&#8230;and penalize them.<\/p>\n<p>Warmy has developed a <strong>proprietary AI called &#8220;Adeline&#8221;<\/strong> to break out of this pattern. Adeline continuously analyzes the metadata generated by the entire network of boxes connected to Warmy (response speed, reading time, deletion, bookmarking) and makes up to 20 million automated decisions a day to calibrate the behavior of each individual box.<\/p>\n<figure id=\"attachment_67432\" aria-describedby=\"caption-attachment-67432\" style=\"width: 2048px\" class=\"wp-caption alignnone\"><img decoding=\"async\" class=\"size-full wp-image-67432\" src=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-scaled.png\" alt=\"\" width=\"2048\" height=\"1227\" srcset=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-scaled.png 2048w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-300x180.png 300w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-1024x614.png 1024w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-768x460.png 768w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-adeline-1536x920.png 1536w\" sizes=\"(max-width: 2048px) 100vw, 2048px\" \/><figcaption id=\"caption-attachment-67432\" class=\"wp-caption-text\">Adeline is also a conversational AI to whom you can ask questions at any time.<\/figcaption><\/figure>\n<p>The underlying network is made up of real mailboxes (1 million+ accounts, according to Warmy anyway), not bots or automated scripts. These accounts send each other emails, read them, remove them from spam, reply to them. To email providers, it looks like normal human activity, because it is, at scale.<\/p>\n<p>Another highlight is its crowd-learning capability. If Microsoft modifies its filtering rules for a sub-group of users, Adeline detects the signal and adapts the heating strategy for the entire network. It&#8217;s this real-time reactivity that sets Warmy apart from a simple dispatch scheduler.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"semantic-heating-by-sector\"><\/span>Semantic heating by sector<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>This is the feature you won&#8217;t find in low-cost competitors, and probably the main reason for choosing Warmy over an alternative half the price<\/strong>.<\/p>\n<p>In 2026, ESPs (e-mail service providers) will no longer simply count the number of e-mails sent. They analyze the semantic content of exchanges to categorize a domain&#8217;s legitimacy. A domain that regularly exchanges terms related to legitimate finance is treated differently from a domain whose emails talk about &#8220;unique opportunity&#8221; and &#8220;click now&#8221;.<\/p>\n<p>Warmy lets you define the thematic sector of your warm-up: cybersecurity, real estate, SaaS, finance, healthcare, e-commerce&#8230;<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-67419\" src=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-warmup-preferences.png\" alt=\"\" width=\"1500\" height=\"804\" srcset=\"https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-warmup-preferences.png 1500w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-warmup-preferences-300x161.png 300w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-warmup-preferences-1024x549.png 1024w, https:\/\/salesdorado.com\/wp-content\/uploads\/2026\/02\/avis-warmy-io-warmup-preferences-768x412.png 768w\" sizes=\"(max-width: 1500px) 100vw, 1500px\" \/><\/p>\n<p>The tool then generates automated exchanges in your industry&#8217;s professional vocabulary, in over 30 languages.<\/p>\n<p>The most striking example is that of cybersecurity: a legitimate email from a company in the sector contains terms such as &#8220;phishing&#8221;, &#8220;vulnerability&#8221;, &#8220;threat&#8221; and &#8220;firewall&#8221;. To a conventional spam filter, this lexical density is immediately suspect.<\/p>\n<p>By training your domain to exchange this vocabulary naturally with real boxes that answer and move your emails out of spam, Warmy &#8220;educates&#8221; providers&#8217; algorithms to recognize your domain as a legitimate sender of this type of content.<\/p>\n<div class=\"blocTips primary-light\"><i class=\"fa fa-lightbulb-o\"><\/i><br \/>\n<span class=\"title is-5\"><span class=\"title is-5\">Salesdorado&#8217;s opinion<\/span><\/span>&nbsp;\n<p>If you send <a href=\"https:\/\/salesdorado.com\/en\/inbound-marketing\/b2b-emailing-campaigns\/\">B2B email campaigns<\/a> in a sensitive sector (finance, health, cybersecurity, legal&#8230;), this feature alone justifies the cost of Warmy. Without semantic warming, you&#8217;ll be at a structural disadvantage that neither the best copywriting nor the cleanest list will be able to compensate for.<\/p><\/div>\n<h3><span class=\"ez-toc-section\" id=\"%e2%80%9cwarmup-with-clicks\"><\/span>&#8220;Warmup with Clicks<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>An open or a reply is good. A click on a link in the email is even better for ESP algorithms, which interpret it as a strong signal of genuine interest.<\/p>\n<p>Warmy has developed a feature that goes so far as to simulate this behavior: network accounts open emails, click on embedded links, and browse briefly.
