Best Maildoso Alternative for Email Deliverability: Maildoso vs Aerosend

It’s not news that Maildoso can be highly unreliable. This is because they share IPs among their users, which means that if they make a mistake, you suffer too. That’s one of the reasons why getting a Maildoso alternative is important.

To elaborate, shared IPs are bad for cold emailers because you could do everything write, have a great offer, follow all deliverability rules, clean your list properly, but if someone else in your shared IP system does not, you get punished too.

Aerosend is the Maildoso alternative you need to send bulk cold emails.

Aerosend offers fully isolated inbox clusters for every 10 domains, built on aged IPs with automated rotation and advanced warmup. Real-time domain burn alerts add another safeguard, which makes Aerosend a stronger and one of the most reliable alternatives to Maildoso.

Shared Servers: Why Aerosend is Better Than Maildoso

If you share sending servers with other users, you might as well send from the same inbox.

Shared IPs have become a major limitation in 2025 for cold email senders. When multiple users share the same IP, one sender’s poor practices can harm everyone’s deliverability. Experienced senders now prefer dedicated infrastructure for consistent inboxing and full control.

Maildoso still relies on shared IPs and exposes users to shared reputation risks. AeroSend eliminates that by giving each user private IPs, free premium warmup, and faster setup, so you can start sending safely and at scale.

Maildoso versus Aerosend: What to look for in a Maildoso Alternative?

• Scaling: Scaling becomes a problem with Maildoso because of the aforementioned risks. A strong alternative should offer dedicated IPs, inbox isolation, domain rotation, and dynamic IP cycling. Real-time blacklist monitoring and sender reputation tracking are essential to stay ahead of deliverability issues.
• Flexible pricing and accessibility: Maildoso requires a 3-month upfront payment, which can feel restrictive for startups or smaller teams testing the waters. Look for MailDoso alternatives like Aerosend that offer flexible monthly billing so you’re not locked in before knowing how well the platform fits your needs.
• Faster setup times: Some users report delays of up to 24 hours before Maildoso accounts are fully configured. In cold email, speed matters, and platforms like Aerosend get you sending within minutes, not days.
• Responsive customer support: Timely help can make or break a campaign. Maildoso users have noted slow responses to critical issues, sometimes waiting a full day for replies. A dependable alternative should have responsive, knowledgeable support ready when you need it (which we do).
• Free premium warmup and automation: Aerosend includes premium warmup for every inbox at no extra cost. It automates ramp-up so your domains stay healthy while you focus on outreach.

Why Is Aerosend the Best Maildoso Alternative

Most “Maildoso alternatives” solve one problem but not all. Running cold email at scale requires infrastructure optimized for deliverability, not shared sending environments.

• Full isolation instead of shared IPs: Maildoso uses shared servers, which means your deliverability can suffer if another user spams or gets flagged. Aerosend gives each user private infrastructure, so someone else’s activity does not influence your reputation.

• Premium warmup included: Maildoso offers no built-in warmup. Aerosend provides free premium warmup on aged IPs, helping accounts build reputation safely from day one without third-party tools or manual fixes.

• Dynamic protection at scale: Aerosend uses automated IP rotation, domain isolation, and burn alerts to prevent sudden drops in inboxing. Maildoso doesn’t provide the same depth of real-time protection or reputation visibility.

• Faster setup and easier operations: Aerosend provisions domains and mailboxes instantly with automated authentication (SPF, DKIM, DMARC, MX). You can start sending within minutes. Maildoso users often face delays of up to 24 hours before accounts go live.

• Predictable performance and control: Because Aerosend avoids shared servers, your deliverability is stable, traceable, and fully under your control, something Maildoso’s shared setup can’t guarantee.

Aerosend replaces the limitations of shared infrastructure with a dedicated, scalable system designed specifically for cold email. It lets you focus on outreach while the platform maintains domain health, warmup, and inbox performance.
