Got a good deal on yearly plan

I was looking for a new email solution for cold outreach and found Maildoso. I signed up for their Outbound Mailboxes on the yearly plan because it was 20% off. That made it a pretty sweet deal compared to paying monthly, which was important for my budget. The setup was quicker than I expected. So far, it seems worth the money.

Good for deliverability, minor setup issue

I got the Google Workspace Cold Email Mailboxes plan a few weeks ago for my team. The deliverability has been really solid, much better than what we were seeing before, which was the main reason for switching. Setting up the custom domain email hosting was pretty straightforward too. The only small hiccup was one of the mailboxes took an extra day to provision, but support cleared it up quickly when I messaged them. Overall, a good experience and it's doing what we needed it to.

They say it's automated, and it really is. Pretty instant if you're already set up with them.

hey, anyone used maildoso mailboxes for their cold outreach? trying to figure out if it's really better than just getting google workspace accounts myself.

M Mark N. 2 months ago
Yeah, I switched last quarter. The deliverability is noticeably better, and the setup for SPF/DKIM is way easier. Plus, if you're doing a lot, they're built for it.

I've heard good things, especially for scaling. Direct from Google can get you flagged faster if you're not careful with warming up, which Maildoso supposedly handles better.
