General information about Warmbox

Warmbox proposes the increase in deliverability of commercial emails. To do this, the solution is to warm up your mailbox to act on its reputation. This way, your emails will arrive safely and can be read by your prospects and customers. Warmbox provides you with a private network of over 10,000 inboxes from over 100 countries. These inboxes then interact with each other to enhance their reputation.


When sending a commercial email, the main obstacle of undeliverability is the classification of the email as spam. This is because mailboxes use a spam filter to protect users from unwanted content. To do this, three elements are taken into account by the algorithm: the reputation of the sender, the activity of the sending mailbox, and the content of the incoming mail. To boost the effectiveness of your communication, Warmbox acts on three criteria simultaneously. You can thus reach your audience and fine-tune your commercial communication with complete peace of mind. Once connected to your favourite email service, Warmbox will indeed warm up your mailbox by interacting with it. This improves its reputation with email services. You will be able to monitor the effectiveness of your actions and the rate of mail opening thanks to detailed reports offered by this very relevant tool.


The strength of Warmbox is that it is compatible with all email services on the market. Whatever the ecosystem or tools you use, this solution is relevant to boost the effectiveness of your email campaigns, newsletters, or webinar invitations.

    Warmbox: Excellent from Sales to Execution

    I found Warmbox to be excellent from the sales process to the completion of the new boiler installation. There was an issue with the plumber cancelling, but Nicole promptly handled it and ensured the job was completed satisfactorily. I, Mick, am happy with the service.
