Questions & Answers

As answered by people managing MailDeck and Close.

Who are some of the biggest customers of your product?

MailDeck's answer

B2B SaaS companies running outbound sales Lead generation agencies managing multiple client campaigns Recruitment firms doing high-volume candidate outreach Growth agencies handling outbound for portfolio companies Sales teams at fintech and real estate companies

What makes your product unique?

MailDeck's answer

MailDeck combines Google Workspace, Microsoft 365, and SMTP providers into a single infrastructure platform. Unlike tools that only handle one provider, MailDeck gives you unified management with automated DNS setup - no manual configuration of SPF, DKIM, or DMARC. It's built specifically for cold email at scale, not repurposed from marketing tools.

Why should a person choose your product over its competitors?

MailDeck's answer

MailDeck focuses on reliability at high volume. Where other providers start having deliverability issues as you scale, MailDeck maintains consistent inbox placement even at millions of emails per month. The zero-configuration setup means you're operational in minutes. Plus, it integrates with any sequencer you're already using.

How would you describe the primary audience of your product?

MailDeck's answer

B2B outbound teams who send at scale - SDRs, sales teams, lead generation agencies, growth agencies, and recruitment firms. Typically teams sending 100K+ emails per month who've outgrown basic Google Workspace setups and need infrastructure that won't collapse under volume.

Which are the primary technologies used for building your product?

MailDeck's answer

MailDeck integrates directly with Google Workspace and Microsoft 365 APIs, along with custom SMTP infrastructure. The platform handles automated DNS management, real-time deliverability monitoring, and smart routing across multiple providers.
