Scaled Outreach Smoothly While Keeping Multiple Sending Environments Organized

We run outreach for several clients at the same time, so keeping everything organized is important. What I like most is that we can manage different sending environments without creating extra work for the team. Over the last 4 months, we've scaled from 12 to 38 active mailboxes and the process has been fairly smooth.

Cost-Effective SMTP Performance, Recommended for Outreach

I was really impressed with the performance of the SMTP mailboxes on Maildoso. In our tests with 10 SMTP mailboxes versus 10 Google Workspace accounts, the SMTP consistently delivered better results while being more cost-effective. I also appreciate the flexibility that Maildoso provides; being able to test different mailbox options on the same platform made it easy for us to compare and determine the best setup for our campaigns. The initial setup was fairly straightforward too.

Stability and Efficiency Restored Our Email Campaign Performance

I appreciate Maildoso's overall stability of the infrastructure which has made our campaigns run consistently over time. We no longer worry about the system randomly breaking and having to rebuild everything. The onboarding flow feels smoother, and their support for Google Workspace and the API has made it easier for our team to manage campaigns without dealing with technical issues. The platform felt more stable compared to our previous experience. They also added new features like monthly plans and better integrations, which helped us manage outreach at scale. Our reply rates have improved, been better at around 5% lately, and I don’t constantly worry about the system randomly breaking anymore.
