Why choose Mailivery?
When it comes to cold emailing or outbound campaigns, deliverability is everything. It doesn’t matter how good your pitch is if your email never makes it into your target’s inbox.
Mailivery is a deliverability improvement tool designed to ensure your emails land where they should inside the inbox. It uses real inboxes to open, reply, and positively engage with your emails, which helps email service providers (like Gmail, Outlook, etc.) mark your domain as trusted.
Rather than guessing whether your emails are being flagged as spam, Mailivery runs daily deliverability checks and actively warms up and protects your sending reputation. This is critical whether you're just starting outbound sales or managing high-volume campaigns at scale.
How Mailivery works
Here’s the simple version of what Mailivery does:
- Sends emails from your account to a network of real, monitored inboxes
- Receives, opens, and replies to your emails automatically
- Moves any emails that accidentally land in spam back to the inbox
- Gradually increases sending volume to warm up new domains safely
- Builds positive engagement signals with email providers over time
- Provides a live dashboard to monitor deliverability metrics and progress
In short, Mailivery simulates natural, healthy email behaviour that email services look for when deciding whether to trust a sender. Over time, this boosts your sender reputation and improves your chances of landing in the inbox.
Why deliverability matters for founders
If you’re running cold email campaigns whether for sales, partnerships, fundraising, or PR poor deliverability can silently destroy your results.
Even with the best copy and perfect targeting, if you're landing in spam folders, you’ll see lower open rates, wasted leads, and missed opportunities. Worse, damaged domains can take months to recover or may become permanently tainted.
That's why serious founders invest early in protecting and strengthening their deliverability, and why using a tool like Mailivery can pay off dramatically over time. It protects your domain’s health, improves your cold outreach performance, and ultimately increases your revenue potential.
