Cold Email Open Rates: How to Improve Cold Email Open Rates in 2025. Cold email remains a vital tool for sales and marketing teams seeking to connect with new prospects. But in 2025, getting people to open cold emails is tougher. Email providers have added more privacy features and spam filters. Also, people get more emails than ever. To stand out, you need more innovative and clearer strategies. This guide shares five ways to improve cold email open rates using MailOptimal’s features to help you get more results.
What Is a Cold Email Open Rate?
A cold email open rate shows how many people open your email out of all the emails you send. Used to be, open rates were around 40% or more. But now, due to recent email provider changes, many block open tracking. Spam filters can also mark emails as spam before the recipient sees them.
Today, open rates are still valid but less precise. It’s better to track who clicks links or replies to your emails to know if your campaign is working.
How to Improve Cold Email Open Rates
1. Use Email Warmup and Focus on Deliverability
If your emails end up in the spam folder, no one will open them. MailOptimal helps you warm up your email by slowly building your reputation. It does this by sending and responding to emails automatically, demonstrating to providers that you send real emails that people want.
Warming up your email is the first step to making sure it lands in the inbox and gets opened.
2. Write Personalized and Clear Subject Lines
The subject line is the first thing people see. Using the recipient’s name or company name grabs attention. Keep it short—between 4 and 7 words. Avoid words that sound like spam.
MailOptimal’s analytics help you test different subject lines and find what works best.
3. Improve Your Preview Text
When people see your email in their inbox, they also see a short preview. This must make them curious to open the email. Use simple, friendly words. Highlight the benefit or ask a question related to their needs.
4. Send Emails at the Right Time
The time when you send emails matters. Find when your audience is most active. MailOptimal’s predictive tools can suggest the best times to send emails based on past data to increase your chances of getting opened.
5. Clean and Segment Your Email List
Sending emails to the wrong or inactive people hurts your reputation. It lowers your open rates. Use lists that are up to date and split them into groups by industry, role, or interest.
Segmented lists let you send emails that match what each group cares about, which means more opens.
