Inboxlogy has a 4.5/5 rating on Trustpilot (28 reviews).

"Inboxlogy: Requires manual setup, leading to a lot of back-and-forth just to make basic changes. Pricing is at $3 per mailbox." — Inboxlogy / Zapmail — Are they trustworthy?

"It's not $3/mo, it's $39/mo for 10 Gmail emails. If you need just 2 inboxes you'll pay $39 instead of $14 by going straight with Google. Total scam." — Inboxlogy / Zapmail — Are they trustworthy?

🟢 Long track record: They have been in the industry for 10 years and have a large client base.

Maildoso isn’t a complex management suite or a sequence builder – we know that real outreach needs a rock-solid foundation. We understand how the inbox works way better than those "all-in-one" platforms like Inboxkit. From our self-healing mailbox rotation to automated email deliverability infrastructure checks, we do all the technical "dirty work" for you, so you can stop worrying about the tech and get back to closing deals.

We provide high-authority mailboxes designed to stay healthy for months, not weeks, allowing your outreach team to focus on the 1% of deals that matter rather than the 99% of tech that usually breaks. It’s a specialized environment for agencies looking for a reliable SMTP mailbox for agencies that have graduated from generalist tools.

"For the price point it's been worth it for us. We're sending around 1,500-2,000 emails/day across those 100 mailboxes and reply rates have been decent (2.8-3.2% depending on the campaign, but that's more about copy and targeting obviously). The infrastructure has been stable enough that i'm not constantly putting out fires anymore which was the whole point." (Reddit)

"Checking back in after another 14 days of volume. We’re officially at 500 mailboxes now and the infrastructure is holding up remarkably well. Only 14 boxes are currently in the "cooling off" period, which is less than 3% of the fleet (totally manageable). Reply rates are hovering at 2.3%, keeping our cost per reply at that $0.10 mark. Honestly, the biggest win so far isn't just the price, it’s the lack of "clustering" issues that usually plague us at this volume on GW. (Reddit)"

🟢 Dynamic IP Rotation: We don't just "aim" for the inbox – we engineer it. Our system automatically rotates your IP addresses in real-time. If an IP gets flagged or blacklisted, we instantly swap it for a clean one before your campaign takes a hit, ensuring your emails consistently land in the primary inbox rather than getting stuck in spam.
🟢 Self-Healing Rotation System: An automated resting period for mailboxes every two weeks that clears provider flags and recovers reputation on autopilot.
🟢 Hybrid Flexibility: The ability to seamlessly blend high-authority Google Workspace accounts with high-volume SMTP mailboxes.
🟢 Global Customer Domain Tracking: Proprietary technology that allows you to safely include links without compromising your sender reputation.
🟢 Automated Inbox Placement Tests: Free email deliverability infrastructure testing every three days for all mailboxes, giving you real-time visibility into your health.
🟢 Unlimited Technical Audits: Free live sessions with experts who resolve up to 80% of issues through deep server-level forensic audits.
🟢 Advanced Captcha Protection: Technical barriers that shield your outreach domains from being linked back to your primary corporate assets.

🔴 Conservative Limits: We suggest sticking to 15 emails a day per box to keep your domains healthy for the long run. You are free to send more if you choose, but be aware that aggressive "blasting" is a fast track to burning your reputation.
🔴 Google/SMTP Focus: We do not support native Microsoft 365/Outlook environments at this time.

When you evaluate cold email providers, you have to look at the underlying technology. A few years ago, you could buy basic Google Workspace accounts, warm them up, and send thousands of emails. You cannot do that anymore. Google and Microsoft use AI to track sending patterns. If your infrastructure relies on static IPs or leaves an obvious footprint, the spam filters will catch you.

This is where Maildoso.ai changes the game. We use intelligent IP rotation. The system constantly shifts the IP address you send from. Spam filters cannot easily tie your domain to a single, burned IP address.

We also use self-healing mailboxes. In a normal setup, if Google flags one of your inboxes, your campaign stops. You have to log in, figure out what went wrong, and fix it manually. Maildoso.ai automates this. The system detects the problem, pauses the bad inbox, runs a recovery protocol, and routes your emails through healthy inboxes. Your campaigns keep running, and you do not lose a day of sending.

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:

1. 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.
2. 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.
3. 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.

Inboxlogy is a massive company with a long history, but their tech is outdated. Dealing with manual setups and emailing support just to change a DNS record slows you down. Maildoso.ai gives you a modern, automated system. You get the accounts you need, plus the IP rotation and self-healing tools required to actually keep your campaigns running.
