Rating & Reviews
The guy who owns EndyInboxes frequently posts here, but he isn’t salesy with his approach and gives good information. They also offer domain health checks, however they are the most expensive.

Maildoso Review
Maildoso is an outbound infrastructure provider built around dedicated IPs, white-glove deliverability onboarding, and a flat per-mailbox model with no per-account cap. It is designed for sales and demand-gen teams that need predictable inbox placement at scale without operating their own mail servers.
Maildoso Pros
- Dedicated IPs from day one — no shared-pool contamination from neighbouring senders.
- White-glove onboarding with deliverability engineers; SPF, DKIM, and DMARC configured for you.
- Flat per-mailbox pricing with no monthly send cap and no per-account markup.
- Direct support from a team that operates mail infrastructure, not generic ticket triage.
Maildoso Cons
- Higher entry price than shared-IP services aimed at single-mailbox use.
- Designed for teams sending at scale; overkill for one or two mailboxes.

Scaling cold email is hard. You buy domains, set up mailboxes, and wait two weeks to warm them up. Then a spam filter flags your IP, and you have to start over. It wastes time and kills your reply rates. You need a reliable infrastructure that scales without burning your budget. Most providers sell basic accounts and leave the heavy lifting to you. Finding a setup that actually keeps you in the primary inbox is the real challenge.
This article compares two cold email infrastructure providers – Maildoso.ai and Endy Inboxes – to help you decide which one fits your outreach operation.
Key Takeaways
Endy Inboxes Review
Endy Inboxes builds private cold email infrastructure. They replace standard Google and Microsoft accounts with their own proprietary system running on dedicated US IPs. They target agencies that want zero technical work. You pay them, and within 30 minutes, they register your domains, configure your DNS, and connect the inboxes to your sending tool. It is a premium, hands-off service.
The True Cost of Bad Deliverability
Do not choose a provider just because they offer the cheapest inboxes. Cheap infrastructure always costs more in the long run. When your deliverability drops, you pay for it in three ways:
- You burn expensive leads. Good B2B data costs money. If your emails land in the spam folder, you waste those leads. You pay for contacts who never even see your pitch.
- You destroy your domains. Once spam filters flag a domain, it is incredibly hard to fix. You usually have to throw the domain away, buy a new one, and start the warm-up process all over again.
- You lose revenue. Every email that goes to spam is a missed meeting. In B2B sales, missing one connection can cost you thousands of dollars in closed revenue.
You have to treat cold email infrastructure as an investment. Maildoso.ai gives you the technical tools to protect your domains and keep your emails in the primary inbox. It is the only way to scale outbound sales profitably.
Final Thoughts
Endy Inboxes is a solid choice if you want a premium, hands-off setup and are willing to pay top dollar for dedicated IPs. But their high prices and lack of automated recovery tools make scaling difficult. Maildoso.ai gives you a better technical foundation. You get automated setup, IP rotation, and self-healing mailboxes at a price that actually lets you scale.
