Email warmup is the process of gradually increasing the volume of emails sent from a new email account or IP address to improve its reputation and deliverability. The objective is to earn the trust of email providers and recipients so that your emails have a higher likelihood of landing in the inbox rather than the spam folder.

What is email warmup
Why is email warmup necessary?
Email warmup is essential for improving email deliverability, especially if you are planning to use the account for mass emailing or marketing campaigns. Email service providers use a variety of algorithms to evaluate the credibility of an email sender. A sudden large volume of emails from a new account or IP address is often flagged as suspicious, leading to poor deliverability or even blacklisting.
How does email warmup improve deliverability?
Email warmup improves deliverability by building a positive reputation for your email account or IP address with email service providers (ESPs). As you gradually send more emails that are opened, clicked, and positively engaged with, ESPs become more confident that you're a legitimate sender, thus increasing the likelihood of your emails landing in the inbox rather than the spam folder.
What are the best practices for email warmup?
The best practices for email warmup include:
- Starting with a small volume of emails and gradually increasing it.
- Sending emails to addresses that are most likely to engage positively.
- Monitoring metrics like open rates, bounce rates, and spam complaints.
- Staggering your sending times.
- Adhering to general email guidelines like providing an opt-out link and avoiding spam-triggering language.
Can I automate the email warmup process?
Yes, the email warmup process can be automated. Specialized tools and services such as Inboxy are designed to automate the sending of warm up emails at a predetermined, gradual pace. However, it's important to monitor metrics and make adjustments as needed, as automation doesn't entirely remove the need for oversight.
How long does it take for an email warmup to be effective?
The effectiveness of an email warmup can vary but generally ranges from a few days to several weeks. This depends on factors like the email service provider, your email list quality, and your adherence to best practices. With Inboxy, you can expect a well-executed warmup and see improvement in key metrics like open rates and deliverability within 14 days or less.
What are the consequences of not warming up an email?
Not warming up an email account or IP address can result in poor deliverability, including emails landing in spam folders. Your email account may also get flagged or even blacklisted by email service providers, which would severely compromise future email campaigns.
How much does email warmup cost?
inboxy warmup is sold as plans: Starter is $39/month for 10 inboxes, Growth $99 for 30 and Pro $299 for 100, with extra inboxes at your plan's rate. Quarterly billing saves about 10% and yearly gives 2 months free. Warmup works on inboxy mailboxes or inboxes you already own. See warmup pricing.
