"Mailivery saved us"
The best part of my experience using Mailivery is that it works. I started sending cold emails without doing the research, and tanked my business' domain reputation. We weren't even able to contact our engaged prospects! After just a few weeks using Mailivery email warmup, I'm already seeing a drastic improvement in email deliverability.
"Best Email Warmer To Exist To Date For Strengthening Domain Reputation"
Amazing, their customer service has improved 10x since we first started and it's been just about 6 months since we have been with them. It's a team you can rely on. So don't think another minute and sign up!
"Wow! Landing in the inbox"
It's super easy to connect my email accounts and the stats that are shown are super useful. The automated reading and sorting feature has made my life so much easier and really separates Mailivery from other products. Overall it's way better than any other warming software I have used.
Frequently Asked Questions
If you are hesitating, do not worry - we are here to explain
everything you might want to know. Let us help!
What exactly is Mailivery warm-up doing?
Mailivery connects to your mailbox and exchanges warm-up emails with other inboxes in our network. It checks if your warmup emails end up in spam or promotions tab. If they do, Mailivery moves them to the main inbox, marks them as safe, and replies to them positively. This process helps convince spam filters that your emails are trustworthy and improves your email delivery.
How does your pricing plan work with sharing emails per day?
Our pricing structure is straightforward: connect as many mailboxes as you like as long as it's within the plans daily warm-up limit. Unlike other warmup services, we won't charge you for each email account you connect.
For example, if you subscribe to the professional plan with 600 warm-up limit per day, you can connect 60 mailboxes at 10 warm-up emails a day for each mailbox (totaling 600) or any variation of speed as long as total volume is 600 or below.
Do you have an API for email warm-up?
Yes. We offer a REST API that lets you connect mailboxes (Microsoft 365, Gmail, SMTP, SendGrid), start or pause warm-up, adjust daily volume and ramp-up settings, pull health score and activity metrics, and receive webhook notifications for key mailbox and warm-up events.
See the Mailivery API overview and the full API documentation for endpoints and examples.
How many warm-up emails per day do I need?
If mainly sending cold emails, our recommendation is to keep a 1:1 ratio of cold emails to warm-up. So if you're sending 50 cold emails per day, then your warm-up speed should be 50 warm-up emails a day as well. As for reply rate, 30% - 55% is sufficient.
Is a "mailbox" the same as a "user"?
No. A user is person with a unique login credentials to access Mailivery. A user can have multiple mailboxes (which we also refer to as inbox). Thus, a mailbox is one of your email accounts you connect to mailivery for warmup.
Why should I choose mailivery over other services?
Most warm-up tools promise the same thing. The difference is how consistently you can maintain inbox placement as you scale, how much control you get, and whether you can integrate warm-up into your own systems.
Choose Mailivery if you want:
• Reliable warm-up quality at scale: Realistic sending and engagement patterns designed to improve sender reputation over time, not just “send a bunch of emails.”
• More control, less guesswork: Set your daily warm-up volume, reply rate, and schedule so warm-up matches your real sending behavior.
• Built for teams, agencies, and SaaS platforms: Manage many inboxes without turning warm-up into a manual process.
• Visibility into progress: Track reputation signals and placement trends so you know what’s improving and when to ramp.
• An API when you need automation: Integrate warm-up into your app or internal tools, provision and manage mailboxes programmatically, and keep workflows centralized instead of jumping between dashboards.
• A deliverability platform, not just warm-up: Warm-up is one piece. Long-term inbox placement gets easier when you also have the surrounding tools and insights to diagnose and fix issues.
Simple rule to decide:
Pick the service that keeps inbox placement stable as your volume changes, gives you control and reporting, and offers an API if you want to automate warm-up at scale.

Why do you have a daily limit per connected inbox?
Mailivery's P2P email warmup tool is built for responsible email marketers and NOT for spammers who don't follow proper email standards. Therefore, we place a daily email limit per inbox to ensure we can keep a high quality P2P warmup network so our users can see positive impact of email warmup.
We'll continue to evaluate our network performance and increase daily limits per inbox on a quarterly basis if needed.
Our current limit for each inbox is 250 emails per day.
