Frequently Asked Questions

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.

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.

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.

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.

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.

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.

With Inboxy, you can receive a 7-day free trial for warming up your emails. After your free trial, our plans start at $47/month. More information here.
