Think of your email list like a group of friends you want to invite to a party. If some friends move, you wouldn't keep sending invitations to their old addresses. Bounced emails are like those returned invitations. ActiveCampaign helps you clean your guest list. Consequently, it keeps your email efforts strong.
Why Do Emails Bounce? Two Main Types
Emails bounce for different reasons. It's helpful to know the two list to data main types: hard bounces and soft bounces. ActiveCampaign treats them differently. Knowing the difference helps you understand what happened.
A hard bounce means the email can never be delivered. It's a permanent problem. A soft bounce means the email could not be delivered right now. But it might work later. We will explore these more. Thus, understanding the type of bounce is key.
Hard Bounces: Permanent Problems
Email Address Does Not Exist
The most common reason for a hard bounce is that the email address does not exist. This means the email address was typed wrong. Or the person closed their email account. It could also mean it was a fake email address from the start. ActiveCampaign will immediately remove these from your list. Therefore, they are permanently removed.
Domain Name Does Not Exist
Sometimes, the part after the "@" sign is wrong. This is the domain name (like "@example.com"). If "example.com" doesn't exist, the email will hard bounce. This is like trying to send mail to a street that doesn't exist. ActiveCampaign removes these too. Consequently, it's a serious address problem.
Mail Server Error (Permanent)
Occasionally, the email server (the computer that handles emails) for that address might be set up wrong. Or it might have completely shut down. This is a permanent mail server error. Your email can never reach them. ActiveCampaign will remove these. Thus, the server is truly unavailable.
Hard bounces are very serious. ActiveCampaign removes these addresses right away. They know there's no point in trying again. Sending too many hard bounces can hurt your sender reputation. This means your emails might start going to spam folders. Therefore, cleaning hard bounces is crucial.
Soft Bounces: Temporary Problems
Mailbox Is Full
A common soft bounce reason is a full mailbox. Imagine your friend's physical mailbox is stuffed with too much mail. They can't get any new letters. The same happens with emails. Their inbox has no more space. ActiveCampaign might try sending again later. If it bounces multiple times, it becomes a hard bounce. Therefore, it's a temporary storage issue.
Mail Server Is Down
Sometimes, the email server that receives the email is temporarily offline. It might be having technical problems. Or it could be under maintenance. Your email can't get through right now. ActiveCampaign will usually try to send it again a few times. If the server stays down, it might become a hard bounce. Consequently, it's a temporary technical glitch.
Message Too Large
If your email has very big pictures or files, it might be too large. Some email providers have limits on email size. If your email is too big, it will soft bounce. Try to make your emails smaller. This helps them get delivered. Thus, check your email size.
Anti-Spam Filters Blocked It
Sometimes, a receiving email server's anti-spam filters might block your email. This doesn't always mean your email is spam. It might be a temporary issue. Or your email's content triggered a filter. ActiveCampaign might try again. If it keeps getting blocked, it can lead to a hard bounce. Therefore, content can be an issue.
Soft bounces are usually temporary. ActiveCampaign tries to resend these emails a few times. If the problem continues, ActiveCampaign will eventually treat it like a hard bounce. They will then remove the address from your list. This protects your sender reputation. Consequently, repeated soft bounces become hard bounces.
Why ActiveCampaign "Bounces from List" Automatically
ActiveCampaign automatically removes bounced emails from your list for several important reasons. They do this to protect your ability to send emails successfully.
Protect Your Sender Reputation
Every time you send an email, your email service (like Gmail, Outlook) watches you. They look at how many of your emails bounce. If you send too many bounces, they think you might be a spammer. Your sender reputation goes down. Then, your emails might start going to spam folders. ActiveCampaign removes bounces to keep your reputation high. Therefore, it's a crucial protection.
Improve Deliverability
A good sender reputation means your emails are more likely to land in inboxes. This is called deliverability. By removing bounced addresses, ActiveCampaign helps make sure your good emails actually get to people. This means your messages are seen by more people. It makes your email marketing work better. Consequently, it directly boosts email success.
Save Money and Resources
Sending emails costs money and uses computer resources. Every time ActiveCampaign tries to send an email, it uses resources. If an email keeps bouncing, those resources are wasted. By removing bad addresses, ActiveCampaign saves resources. This is more efficient for everyone. Thus, it's a smart use of resources.
Follow Anti-Spam Rules
There are strict rules about email sending. These rules, like CAN-SPAM in the US or GDPR in Europe, aim to stop spam. Sending to invalid addresses can violate these rules. ActiveCampaign's automatic bounce handling helps you stay compliant. It ensures you follow the rules. Therefore, it keeps you on the right side of the law.
ActiveCampaign works hard to maintain its own reputation with internet service providers (ISPs). If ActiveCampaign's users send too many bounces, it hurts ActiveCampaign's reputation. By enforcing bounce management, ActiveCampaign protects its service for all its customers. Consequently, it ensures overall system health.
How to Prevent Email Bounces in ActiveCampaign
Preventing emails from bouncing starts before you even send them. Here are some best practices.
Get Permission (Double Opt-In Is Best!)
Always ask people to sign up for your emails. This is called permission. The best way is double opt-in. After someone signs up, you send them a confirmation email. They click a link to prove their email is real. This greatly reduces fake addresses. Therefore, strong consent is the first line of defense.
Verify Emails Before Sending
Use an email verification service. These tools check if an email address is valid before you send any emails to it. They can find fake or non-existent emails. This helps you clean your list proactively. It saves you from sending to bad addresses. Thus, proactive checking is very helpful.
keep Your List Clean Regularly
Don't just rely on ActiveCampaign's automatic bounce handling. Regularly review your list. Remove inactive subscribers. If people haven't opened your emails in a long time, they might be disengaged. A clean list is a healthy list. Consequently, regular maintenance is key.
Don't Buy Email Lists (Ever!)
Never, ever buy email lists. These lists often contain many fake or old email addresses. The people on these lists never gave you permission to email them. Sending to bought lists will lead to many bounces. It will also hurt your sender reputation badly. Therefore, purchased lists are a major no-no.
Use Clear Sign-Up Forms
Make your sign-up forms clear and easy to use. Make sure people type their email address correctly. You can use simple checks on the form itself. This helps prevent typos. A clear form reduces errors. Thus, good design helps.
Send Engaging Content Consistently
Send emails that your subscribers want to read. If your content is good, people will stay engaged. They won't mark your emails as spam. This keeps their mailboxes active. Consistent, valuable content reduces bounces in the long run. Consequently, content quality matters.
Understanding ActiveCampaign's Bounce Reporting
ActiveCampaign provides tools to help you understand your bounces.
Check Your Campaign Reports
After you send an email campaign, go to its report in ActiveCampaign. You will see a section for bounces. It tells you how many emails bounced. It often breaks down the hard and soft bounces. Reviewing these reports is important. Therefore, check your numbers often.
Look at Your Contact Profiles
For individual contacts, you can look at their contact profile in ActiveCampaign. It will show if they have bounced. It will usually say "Bounced (Hard)" or "Bounced (Soft)." This gives you details for each person. This helps you understand specific issues.
Why ActiveCampaign Suspends Contacts
ActiveCampaign will mark a contact as "Bounced (Hard)" and automatically suspend them. This means they won't receive any more emails from you. This is a good thing for your sender reputation. It's an automatic safety feature. Thus, suspension is for protection.

If a contact has multiple soft bounces over time, ActiveCampaign might also suspend them. They will try a few times. But if the problem persists, they will stop sending. This prevents endless attempts to an unreachable address. Consequently, soft bounces can also lead to suspension.
Segmenting Bounced Contacts
You can segment your list in ActiveCampaign to see all bounced contacts. This allows you to review them. You might see patterns. Perhaps emails from a certain company always bounce. Segmenting helps you analyze. Therefore, it's a good way to monitor.
The Importance of a Healthy Email List
A clean list, free from bounces, is vital for successful email marketing.
Better Delivery Rates
A healthy list means your emails actually reach people. Your delivery rates will be higher. This ensures your message gets to your audience. It makes your marketing efforts more effective. Therefore, a clean list is an effective list.
Stronger Sender Reputation
With fewer bounces, your sender reputation stays high. Email providers trust you more. Your emails are less likely to end up in spam folders. This is essential for long-term email success. Consequently, reputation is built over time.
Improved Campaign Performance
When your emails reach real, engaged people, your campaign performance improves. You'll see higher open rates. You'll get more clicks. You'll likely see more sales or desired actions. This means your time and effort are well spent. Thus, good lists lead to better results.
