How does it work, briefly ?

Your email account will automatically send dozens of emails to Mailwarm (+1000 email accounts), on a daily basis at the right frequency, and will be marked as non-spam if so, get starred, and get replied. By doing so, your IP reputation will raise and keep your emails away from spam !

I'm a newbie at IP reputation, spam and so on, could you tell me more about it ?

Sure, everything is explained here in this blogpost.

Do you promise I won't land in spam ?

Reaching inbox is a fine mix between the content of your emails and the activity of your account. We take care of this very last part so we count on you to follow the best practice regarding content, then things will go well for you.

What plan should I choose ?

It depends on your current activity : quantity, frequency & deliverability of your emails. If you have any questions, please contact us.
If your email has been recently created and you plan to send <100 emails/day, we recommend you to start with the small plan (Starter) and then upgrade as you grow.

Do you offer volume licensing for teams?

Yes, we do. If you need Mailwarm for more than 10 email account or more than 500 daily interactions, please reach out to us.

How long should I use Mailwarm ?

Mailwarm raises and keep your IP reputation high which is the key to avoid the spam folder, it's meant to run on a daily basis during your email account life as it's balancing your own activity.

What do you mean by "reputation" ?

Each time you send an email, internet sever providers (e.g. Gmail) attribute a reputation score to your IP and domain. This value is based on the content of the email, the age of your account and its sending activity If this score is bad, your emails go into spam or might get blacklisted.

Will my inbox be full of Mailwarm emails ?

Mailwarm is based on generating an email activity between you and us, so you'll receive emails from us (quite a lot). Thanks to a specific word in their content you can create a rule to redirect them directly into a folder, so your inbox will stay clean.

What kind of emails are sent ?

The content and the length of the emails are optimized to raise your account reputation, they don't bring valuable information. Replies will be stored in a dedicated folder so you won't be bothered with them.

Does Mailwarm sends and receives emails with my account ?

A traditional email account is built with a sender part (SMTP) and a receiver part (IMAP). Emails will be sent through your SMTP to Mailwarm's accounts, which will reply according to the reply ratio you set (30% is recommended).
