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
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.
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.
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.
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.

The author disagrees with you https://github.com/imapsync/imapsync/issues/257#issuecomment-741225371 is because: - I earn my leaving from imapsync buyers but less likely on donators, as a measured fact. - Donations work 1/100 less than payments, ie, for $1 from donators I get $100 of buyers. - I don't make the github release, Nicolas does, and Nicolas doesn't include the .exe binary in the repository, it is a... - Source: Hacker News / over 1 year ago

Another happy Purelymail customer here (5 years). If anyone needs to move mail storage from one IMAP server to another (eg; Purelymail) I can highly recommend https://imapsync.lamiral.info/ Not for it's website graphic design, but as a CLI tool that works perfectly. "source server -->> target server" and let it run. - Source: Hacker News / over 1 year ago
