Cost-Effective Scaling with Effortless Integration

I really appreciate that Maildoso is built for scale. We run about 400 mailboxes through it, and the cost savings we get compared to Google Workspace or Microsoft 365 are huge. The one-click integration with our sequencer made getting started very easy. The SMTP setup makes it easy to handle large volumes without things breaking, so I don't have to worry too much about managing individual mailboxes.

Easy Google Mailboxes, but Support Takes Forever to Respond and resolve issue

They offer Google mailboxes for cold outreach and it's easy to integrate on Smartlead.

Effortless Email Scaling, Exceptional ROI with Maildoso

I appreciate Maildoso's pricing, which keeps our costs around $2 to $2.50 per mailbox while including both SMTP and Google Workspace. This is a very good deal from my experience. I also like the automated DNS setup (SPF/DKIM), which saves a lot of back and forth with the technical team. Another aspect I like is the simplified setup, which makes sending at scale much more reliable. The initial setup was pretty straightforward thanks to the automated DNS configuration.
