ZeroBounceCase Studies

Sender reputation is how ISPs view your email domain. Domains with high bounce rates, low engagement, and frequent spam reports have a poor sender reputation. This causes more emails to bounce regardless of content.

You can strengthen your sender reputation with these tactics:

An email is only as good as the content inside. Once you're confident you'll reach the inbox, you need to make every message count.

Test different subject lines and body content to determine what receives the best engagement among your subscribers. Keep a consistent style and personalize each message to the user as well as the audience segment.

Focus each email on one idea and avoid overburdening the reader with information. Break up content with eye-catching images and ensure they properly load once they reach the inbox.

Content and engagement go hand-in-hand. However, some users will never open your emails. They automatically delete your message and move on to the next.

ISPs recognize this pattern and use it to impact your email deliverability. Instead of reaching the inbox, your message may automatically head to subfolders like Promotions or Spam. Look out for unengaged subscribers and delete them from your mailing list.

Also, look out for any abuse emails. These are users that misuse the spam report function to flag your domain unfairly. Scrub these from your list using an email validation tool as soon as possible.

Email security tools like SPF, DMARC, or DKIM help to protect your email domain from spammers and spoofers. However, improper implementation of these tools can affect your ability to send and receive emails.

Always test emails after configuring your email security settings. When your company roster changes, or if people switch roles, be sure to update your approved addresses and IPs. This helps with deliverability and keeps your security up-to-date to deny would-be attackers.

The length of your content affects subscriber engagement. A longer email also causes email file size to increase. ISPs dislike large email files as they negatively impact the user experience. This can lead to long load times or failure to load content properly.

Email length is variable depending on your immediate goal. Keep your email length concise. Focus on one offer that allows the reader to get the message. If you need to provide additional information, give the reader the option to find out more through a link or button.

Your users receive countless emails daily. Respect their time by keeping your email length appropriate, making them more likely to interact with your content.

Email verification is the only way to determine if a real person uses an email address. By verifying an email, you ensure that the address is valid and that a person will engage with your content upon receipt.

Sending emails to verified email addresses is the best way to improve returns on your email campaign efforts. It also identifies unverified emails that can negatively impact your performance, harm your sender reputation, and potentially land your domain on a blacklist.

Every email lead a company obtains has a cost. Brands spend set amounts monthly in PPC advertising, organic marketing, and social media marketing to acquire new leads.

You can estimate the cost of an email by comparing how many emails you obtain per month versus the total cost spent to get them in the same period.

The problem is that not all users are honest, and many emails are invalid or unverified.

With your new list of email contacts, you begin a new email marketing campaign with a specific revenue goal. You do this only to find that many emails bounce and some receive spam reports. In a worse scenario, your new list has a spam trap designed to catch irresponsible senders. Now your domain is on a blacklist, and you cannot send messages at all.

Companies use

email verification

to protect their email reputation and maximize the value of their marketing efforts. Marketers estimate that email makes up as much as 60% of their annual revenue.

It's essential to identify unverified, harmful addresses before you begin a new email campaign to make sure every dollar spent counts.

Absolutely. There are zero downsides to using email verification, and it's the only way to protect your company's email reputation.

It's common for your list to pick up invalid or toxic email addresses. Additionally, email lists grow stale quickly, with over 20% of your contacts becoming outdated in a year. You should clean your email lists at least every three months. You may want to do this more frequently, depending on how many new leads you receive regularly or if you observe a change in your email performance.
