Compare Warmup Inbox and ZeroBounce features
Both Warmup Inbox and ZeroBounce feature relatively similar email warmup tools. However, here’s some insight into what these features are, why they’re essential, and what’s right for your needs.
Which mailboxes are supported?
ZeroBounce - Connect any inbox that uses SMTP
Warmup Inbox - Connect any inbox that uses SMTP
Both ZeroBounce and Warmup Inbox allow you to warm accounts for any mail account that supports SMTP. Examples of supported platforms include:
- G-Suite
- Office 365 / Outlook
- Yahoo Mail
- AOL
- AWS
Most, if not all, major mailbox providers support SMTP. Be sure to check with yours before committing to an email warmup service.
Daily sending limits, email warmup actions, and account listings
After connecting your mailbox, your warmup tool will begin sending emails to warm up your mailbox and domain. However, your account's limits determine the rate at which this process can yield a positive impact.
Here’s a closer look at how ZeroBounce and Warmup Inbox determine their limits by plan:
Warmup Inbox
Basic plan
75messages sent daily
Replies to your messages up to 25% of the time
A key distinction here is that the two platforms measure your Warmup activity differently.
ZeroBounce focuses on actions, which are the actual activities used to yield positive engagement and improve your domain reputation. These actions are guaranteed and will adjust automatically based on your current performance. They also strive to emulate realistic behavior exhibited by your real subscribers.
Warmup Inbox offers plans with daily sending limits. However, not all of these email messages will receive interaction as per their service description. Similarly to ZeroBounce, it strives to auto-adjust and warm up your mailbox naturally.
Finally, ZeroBounce allows you to share these daily actions across up to 10 different accounts. Warmup Inbox’s daily messages are for just one listing.

Check out WarmupEmail scheduling
Most email warmup tools use AI to intelligently determine the best times to send emails from your account. However, advanced users may want greater control over the process.
Here’s how ZeroBounce compares to Warmup Inbox for this feature:
Warmup includes a self-managed option. By choosing this, you’ll be given a list of seed email addresses. You can then send your real email campaigns and templates to these addresses at your normal or preferred time. Scheduling is entirely in your control.
Warmup Inbox
For basic users, Warmup Inbox automates the email warmup process, including scheduling, for you. However, if you upgrade to their Pro plan or higher, you’ll receive greater customization options in terms of how you send emails.

Adjust your rules as needed: While it’s recommended to use the ZeroBounce-managed method and allow the warmup process to proceed naturally, advanced users can adjust rules at any time.

Use case scenarios
With a detailed email warmup tool comparison complete, here’s the critical question:
Who benefits from using an email warmup tool?
Every business benefits from email warmup, especially when you have a wide variety of persons and teams sending emails using the same domain and IP address. Let’s take a closer look.
Sales and outreach professionals
When developing Warmup, we reached out to a variety of professionals.
It's no surprise that email marketers were familiar with email warmups. And, of course, they always use the best practices.
However, people on the sales side typically don’t think in terms of email deliverability. Your sole focus is on growing your numbers and making the most out of that new lead list.
However, here’s the usual result:
- Many of those email addresses are invalid, which causes high bounce rates
- People who haven’t opted into your message report you as spam
- Your email engagement is poor when compared to the sending volume
- Your sender reputation declines, which impacts EVERYONE at your company looking to generate revenue with email
It’s also vital to communicate that email warmup isn’t meant to aid bad actors. If you’re guilty of these actions, you still need to clean your data and follow best practices. However, even lawful senders can acquire many spam complaints from abusers, so email warmup is always in your best interests.
Here’s the TLDR:
- If you’re regularly adding hundreds (even thousands) of leads to your database
- If you’re not validating those email addresses
- If you’re experiencing high bounce rates
- If you’re not getting the engagement you want
You need to warm up your email reputation to prevent further damage.
Warm up new business domains
Email warmup doesn’t just help with reputation damage; it actively builds your reputation in all cases. This process is particularly useful if you’re starting a new business or creating a new domain that hasn’t sent mass email communications before.
Every business and email domain has a sender reputation. Think of this like a credit score for your email activity. While you may not have bad credit, not having any credit also makes other parties less trusting of you. But as a new business, you need to leverage email communications to start generating revenue.
The TLDR - use email warm up if:
- You just started a new business
- You switched to a new email domain
- You’re rapidly scaling the amount of emails you send to subscribers
Email marketers
While most email marketers are familiar with best practices, that doesn’t mean others aren’t impacting your reputation. You may have sales reps, BDRs, retention specialists, and so on, sending thousands of emails weekly.
If you’re the marketer doing everything right and testing their email campaigns and still facing low engagement, it can very likely be a reputation issue caused by your teammates. Hence, you can benefit from email warm up to counterbalance the damage.
Additionally, connect with the others on your team to educate them on the impact they have with their email behaviors. While email warmup is a necessary component to help you, ensuring everyone is doing their part to earn a better reputation is the key to long-term success.
Use email warmup if:
- You’re looking to improve your email campaigns and drive more engagement
- You want to maximize your inbox visibility and stay out of spam
- You have other team members and departments that aren’t following best sending practices
