Che cos'è Maildoso?

Cold email marketers use it to keep their main site domain safe.
Outreach runs on secondary domains, so your primary business domain never takes the hit.
Here is a walkthrough of the platform in action.

Pricing verified August 2026.
Prova gratuita: No open free trial. You buy a mailbox package and the team provisions your domains.
Garanzia di rimborso: Not published. Ask sales before you commit if refunds matter to you.
📌 Nota: Every tier bundles the domains, mailboxes, and DNS setup together. That is where the cost savings come from versus buying Google Workspace seats one by one.
⚠️ Pricing conflict: Some third-party write-ups list a $99 entry point billed three months upfront. Our CSV records $100/month for the 32-mailbox package, and we use that figure throughout this article. Confirm billing terms on the checkout page.
Ecco perché chi invia email a freddo sceglie Maildoso:
Here is what pulls people toward this platform:
- Automated technical setup: Domains, mailboxes, and DNS records are configured for you. No SPF or DKIM guesswork.
- Master inbox: Replies from multiple email accounts land in one place. You keep conversation history without switching tabs.
- IP rotation: Mail goes out across rotating IP addresses to reduce spam folder placement.
- Bulk domain management: Buy and manage multiple domains from one screen. Domain forwarding points them back to your main site.
- Tool integrations: Connect cold email campaigns to Immediatamente, Smartlead, and other sequencers. Your favorite email client still works over IMAP.
- Cost efficiency: A flat mailbox price is more cost effective than per-seat email providers once you pass a handful of inboxes.
- Proven usage: Over 2,000 customers run cold email outreach on the service.
Cosa ha notato il nostro team
Nostro scrittore bought a small package and ran it for several weeks of live outreach. Here is what stood out:
The same session, recorded end to end:
Il costo per casella postale più basso sul mercato.
✅ Pro
- Automates domain setup and mailbox creation, saving hours of DNS work
- La casella di posta principale gestisce le risposte provenienti da più account email in un unico posto.
- Low cost per mailbox compared to Google Workspace or Microsoft 365
- Rotates IP addresses to improve deliverability and avoid spam filters

❌ Contro

- Customer support has been reported as slow on urgent issues
- AI warm-up is priced separately and scales from $160 to $2000 monthly
Che cos'è Warmy?
Warmy is an email deliverability tool, not an infrastructure host.
You connect the mailboxes you already own and it warms them.
Your mailboxes join a seed network that sends and replies to warm up emails.
Those replies look human, which teaches filters that your domain is safe.
Warmy works on domain warming as well as individual inboxes.
Adeline AI adjusts daily volume so the warm up process never spikes.
This video shows the dashboard and the setup flow.
⚠️ Name clash: Two companies share this name. Warmy.io is the deliverability software reviewed here. The Warmy is a clothing retailer known for oversized hoodie dresses. Reviews about comfort, softness, or shipping delays belong to the clothing brand, not the software.
Caldo
Warm up any mailbox you already run. Free tools include a deliverability test and an SPF record generatore.

Pricing verified August 2026.
Prova gratuita: Yes. A 7-day free trial lets you test the warm up before paying.
Garanzia di rimborso: Not published. The trial is the safety net here.
📌 Nota: Tiers mostly differ by how many warm up emails you send per day. Free tools such as the deliverability test and template checker sit outside the paid plans.
⚠️ Pricing conflict: Public reviews describe five published tiers from $49/month up to $429/month, with a starter plan that leaves out advanced warm-up. Our CSV records three sender-based plans, all quoted on request. We follow the CSV and treat the public figures as historical.
Ecco perché Warmy si distingue come soluzione specifica per il riscaldamento:
Here is what the platform does well:
- AI-run warm up: Artificial intelligence sets the daily ramp for you. Users report the AI-driven approach is the part that impresses them most.
- Deliverability testing: Run a free test and see whether messages hit the primary inbox, promotions, or the spam folder.
- Blacklist and reputation tracking: Track whether your domain gets blacklisted and watch sender reputation move week to week.
- Google Postmaster insights: Pull Google’s own dati into the dashboard for a second read on inbox placement.
- 30+ languages: Warm up in the language your recipients actually read, which matters for non-English email campaigns.
- Template checker: Test copy before you send it. Catch the words and links that push mail toward spam.
- Strong public reviews: Warmy.io holds an “Excellent” 4.6 out of 5 on Trustpilot, with support quality named again and again.

Confronto delle funzionalità
These are two different categories of software, so the overlap is smaller than the names suggest. Both aim at high deliverability from opposite ends. We compared nine key features plus cost.

1. Riscaldamento via email
Maildoso: Warm-up filters keep automated traffic out of your working view. The AI warm-up itself is a separate purchase, and public figures put it anywhere from $160 to $2000 per month depending on scale. Warming is crucial here because the base product ships without it.
Caldo: This is the whole product, not an add-on. It sends warm up emails, opens them, and replies from a seed network so filters see real engagement. You can add your own templates and pick the warm-up topic.
2. Artificial Intelligence and Automation
Maildoso: AI-powered warm-up handles the ramp once you pay for it. Automazione here focuses on provisioning rather than reputation. The system spins up email accounts and rotates sending across IPs.
Caldo: Adeline AI reads your results and adjusts daily volume on its own. Reviewers repeatedly single out this AI-driven approach as the reason they stayed. It is the closest thing either tool has to set-and-forget deliverability optimization.
3. Inbox and Mailbox Management
Maildoso: The master inbox pulls replies from every mailbox into one screen with full conversation history. Run 32 or 400 inboxes and you still work from one view. Nothing similar exists on the other side.
Caldo: There is no reply management layer at all. What you get instead is the email seed list, the pool of real mailboxes interacting with your messages. You keep reading replies wherever you already read them.
4. Domain Setup and DNS
Maildoso: Buy multiple domains inside the platform and let it write the DNS records. SPF, MX, and DKIM are handled during provisioning. Domain forwarding sends stray clicks to your main site.
Caldo: You bring your own domains. The SPF record generator writes correct syntax for you, but registration and hosting stay with your registrar. That means more control if you already have a technical setup you like.
5. Deliverability Testing and Insights
Maildoso: Dedicated mailboxes and IP rotation are the deliverability strategy. There is no placement test to run, so you learn from campaign results. Shared IPs mean other cold emailers on the same address can move your numbers, so better deliverability depends partly on strangers.
Caldo: The deliverability test shows exactly where mail lands across major email providers. You get inbox placement percentages, blacklist status, and bounce rates in one report. This is the clearest window into sender reputation either tool offers.
💡 Consiglio da professionista: Neither service sells a dedicated IP address. If three dedicated IPs are a hard requirement, look at Infraforge or Inframail instead.
6. Setup Speed and Onboarding
Maildoso: Automated setup is the headline benefit. You pick a package, and domains plus mailboxes arrive configured. Buying 68 inboxes by hand through traditional email providers would take a full day.
Caldo: Connection takes minutes, but the payoff does not. Reviewers are consistent that this is not an overnight fix. The template checker gives you something useful on day one while reputation improvement builds.
7. Integrazioni e accesso alle API
Maildoso: Mailboxes connect to Instantly, Smartlead, and similar sequencers over standard protocols. API access and IMAP mean your existing stack keeps working. Nothing forces you to abandon tools you already pay for.
Caldo: Google Postmaster integration pulls Google’s own reputation data into the dashboard. Mailbox connections cover Gmail, Google Workspace, Outlook, and SMTP. It sits alongside your sending tool rather than replacing it.
8. Tracking and Branding
Maildoso: Custom tracking domains keep open and click tracking on your own domains. Generic shared trackers get flagged, so this matters more than it sounds. Setup happens during provisioning at no extra cost.
Caldo: The signature costruttore produces clean, lightweight signatures that do not trip filters. Heavy image-based signatures are a common reason good mail lands badly. It is a small feature with a real effect on placement.
9. Campaign and Sequence Tools
Maildoso: A light CRM tracks replies and contacts from the master inbox. It is enough for basic lead generation follow-up. Serious sequencing still belongs in a dedicated sending tool.
Caldo: The sequence builder handles simple email outreach flows. It is not built to replace Instantly or Smartlead. Treat it as a bonus for smaller companies running light email marketing campaigns.
10. Prezzi e costi
Side by side, only one of these two publishes a number.
| Livello | Maildoso | Caldo |
|---|---|---|
| Iscrizione | 32 Mailboxes — $100/month | B2B Sender — Contact us for pricing |
| Medio | 68 Mailboxes — $166/month | B2C Sender — Contact us for pricing |
| Superiore | 400 Mailboxes — $733/month | Custom Plan — Contact us for pricing |
| Prova gratuita | ❌ | ✅ 7 giorni |
Maildoso: At $100/month for 32 mailboxes, you pay roughly $3 per inbox. Google Workspace at list price would cost several times that for the same count. The catch is billing upfront across months, which stings on a tight budget.
Caldo: Every plan is quoted on request, so you cannot compare cost efficiency before a sales call. The 7-day trial softens that, and free tools let you test value first. Budget for it as an add-on, not a replacement for mailbox costs.
Diversi scenari
| Se hai bisogno | Scegliere | Perché |
|---|---|---|
| Domains and mailboxes from scratch | Maildoso | Supplies the infrastructure itself |
| To fix an existing sender reputation | Caldo | Warm-up is the core product |
| A published price today | Maildoso | Plans start at $100/month |
| To test before paying | Caldo | Prova gratuita di 7 giorni |
| Replies from many inboxes in one view | Maildoso | Master inbox with conversation history |
| Proof of inbox placement | Caldo | Deliverability test and blacklist checks |
💰 Il tuo budget
Maildoso puts a real figure in front of you before signup. Warmy needs a sales conversation first, which slows down anyone comparing cost efficiency across vendors.
🔌 Il tuo stack tecnologico
Already sending from Google Workspace on your own domains? Warmy layers on top without changing anything. Starting clean, Maildoso replaces the whole cold email infrastructure layer.
📈 Your Sending Volume
Agencies that need as many mailboxes as possible will look at the 400-mailbox tier. Smaller companies sending from three or four inboxes get more improvement from warm-up than from more inboxes.
🎓 Il tuo livello di esperienza
Maildoso is more user friendly for beginners because it hides DNS entirely. Warmy asks you to read reputation data and act on it, which has a learning curve.
🆓 Prove e demo gratuite
Start with Warmy’s free deliverability test even if you never buy. It tells you whether your mail already lands in the primary inbox or the spam folder.
🛟 Opzioni di supporto
Support is the clearest split. Warmy reviews name responsive help repeatedly, while Maildoso has been reported as slow to answer urgent tickets.

Cosa non è stato trattato nella nostra recensione
We focused on small teams and agencies running cold email outreach. We did not test enterprise contracts, bulk API access at scale, or long-term sender reputation across a full year. Warmy’s quote-based tiers were not priced through a sales call, so we cannot mark one plan as better value than another. If you send transactional mail or run regulated email marketing, your priorities will differ from ours.

🏆 VINCITORE: MAILDOSO
Maildoso si aggiudica 4 categorie su 7.
Ideale per: Bulk mailbox provisioning, agency outreach campaigns, protecting your primary domain
Maildoso wins because it solves the harder problem. Buying domains, creating email accounts, and writing DNS records by hand is the step most cold emailers get wrong.
Warmy is a solid choice, and for some readers it is the right first purchase. If your mail already goes out but keeps missing the primary inbox, warming beats buying more inboxes.
Honestly, most serious senders end up running both. Maildoso builds the accounts, Warmy makes sure they send emails that get delivered reliably.
