Possible disadvantages

  • Limited Customization
    Some users may find that Mailwarm’s automation features lack the level of customization required for highly specific or complex email strategies.
  • No Instant Results
    The warming process is gradual and can take several weeks to show significant improvements in deliverability, which might not meet the needs of users looking for immediate results.

What's the story behind your product?

Redactable's answer

Redactable was developed to address the growing need for secure, accurate, and automated document redaction in an increasingly digital and compliance-driven world. Recognizing the challenges organizations face with manual redaction methods, Redactable was created to simplify the process, improve accuracy, and ensure comprehensive data security.

Mailwarm's answer:

Mailwarm started as a real problem we faced ourselves.

We were two founders working at Station F in Paris, the largest startup incubator in Europe, trying to sell our own products. Every time we launched outreach campaigns, our emails kept landing in spam.

To solve this, we built an internal email warmup system for our personal use. After deep research into email deliverability, we created a stronger, more reliable solution.

Other startups in the incubator quickly asked to use it too; so we turned it into a real product.

After launching publicly, Mailwarm became #1 Product of the Day on ProductHunt and was accepted into Y Combinator, the world’s most prestigious startup accelerator.

Since then, Mailwarm has grown into a trusted platform used by thousands of companies to improve inbox placement and email deliverability.
