Why Multiple Mailboxes Matter

Distributing your email volume across multiple mailboxes and domains is crucial for deliverability

Protect Sender Reputation

Spreading email volume across multiple mailboxes prevents any single address from being flagged as spam. If one mailbox has issues, others remain unaffected, protecting your overall sender reputation.

Improve Deliverability

Email providers monitor sending patterns. By limiting emails per mailbox, you stay within safe thresholds, ensuring your messages reach the inbox instead of spam folders.

Scale Your Outreach

As your business grows and email volume increases, multiple mailboxes allow you to scale safely. Add more mailboxes and domains without risking deliverability.

Quick Tips

What is the purpose of the Mailbox Calculator?

The Mailbox Calculator helps businesses determine the optimal number of domains and mailboxes they need based on their daily email sending requirements. This tool is essential for planning email campaigns and ensuring efficient use of resources.

Why do you need multiple email addresses?

Using multiple email addresses allows you to spread out your email volume, which can enhance deliverability and reduce the risk of being flagged as spam. It also helps in segmenting different types of communications and can increase the effectiveness of your email campaigns.

How can you warm up multiple emails and domains easily?

Warming up your emails and domains involves gradually increasing the volume of emails sent from new addresses to establish a reputation with ISPs. DitLead automates the warming up of your multiple emails and domains, ensuring better deliverability and performance.

How does having multiple domains benefit my email marketing strategy?

Multiple domains can help protect your sender reputation by isolating potential issues to one domain at a time. If one domain encounters deliverability problems, your other domains continue to perform well, maintaining overall campaign effectiveness.

How often should I review my domain and mailbox needs?

It's a good idea to review your needs whenever there is a significant change in your email sending strategy or volume. Regular reviews ensure you're always optimized for maximum deliverability and efficiency.

What's the recommended email sending limit per mailbox?

We recommend sending 30-50 emails per mailbox per day for optimal deliverability. This conservative approach helps maintain a positive sender reputation and ensures your emails consistently reach the inbox.
