Frequently Asked Questions

Everything you need to know about MailDeck's cold email infrastructure.

What is MailDeck?
MailDeck provides fully configured, official Microsoft inboxes for reliable cold email outreach without the hassle of technical setup or high costs.
Recommended Amount of Sending?
To avoid spam filters, each inbox should send only 5 cold emails per day. With multiple inboxes, you can scale your outreach efficiently. Never send above 2,000 emails total/tenants so for example 5 cold, 7 warm/day *100 = 1,200 sends/day is our personal recommendation. Example: 5,000 accounts (50 tenants) allow you to reach 25,000 potential clients DAILY.
How Does MailDeck Guarantee Deliverability?
MailDeck guarantees all accounts to be configured with optimal DNS, DKIM, and SPF settings to enhance deliverability. Additionally, we actively monitor deliverability rates and DMARC records. If a tenant/domain goes bad let us know and we'll replace it for you.
What's the Difference from Outlook Accounts?
No difference they are the same licences and same accounts in terms of sending cold emails. The only difference is the price you pay is 20x cheaper.
Can I Bring My Own Domain?
Absolutely, you can bring your own domains or if you need help picking domains, we will provide you them as well at $12/domain.
Is This Right for My Business?
If your ideal customers are reachable by cold email, MailDeck is ideal. Whether you're an agency, solopreneur, or SaaS founder, our service can help you reach hundreds of thousands of potential clients daily.
