Whether you’re sending sales or marketing emails, reducing your email bounce rate can be a bit of a head-scratcher. But it doesn’t have to be. Most of the articles I’ve come across tend to lump it all together. But, in my experience, not all emails are created equal. Which brings me back to the whole “sales and marketing” thing. Frequently, the root causes of a high email bounce rate are the same for both, but with a few potential differences for either. It really comes down to the idea that sales and marketing emails are different. By treating them as one, you can end up tunneling on a fix that’s always going to be beyond reach.
Get the basics right and you’ll be in good shapeHere’s a cheat-sheet if you’re too busy hustlin’ to read through all of these juicy pointers In short, there are no 100% guaranteed ways to reduce your email bounce rate. That said, if you follow just a handful of these tips make it these:
- Get permission from your users
- Let them control permissions
- Verify your domain
- Send non-spammy emails, consistently
- Use a quality email marketing platform
What is email bounce rate?Others have written it before me and probably better than I could write it if broke out the thesaurus, so I’ll let Webopedia take the stage here:
In email marketing bounce rate refers to the percentage of email addresses in your subscriber list that didn’t receive your message because it was returned by a recipient mail server. There are two categories of email bounces including hard bounce and soft bounce. WebopediaSo, if you wanted to calculate your email bounce rate, that calculation would be: (# of bounces* / # of delivered emails) x 100 = your email bounce rate
Hard bounceA “hard” bounce means an email has bounced back to the sender undelivered without having been accepted by the receiving email server. The “standard” given reasons for a hard bounce are…
- The email address doesn’t exist
- The domain doesn’t exist
- The receiving email server has completely blocked delivery.
Soft bounceWhen e-mailing, a soft bounce is used to describe an e-mail that has bounced back to the sender undelivered after it has already been accepted by the recipient’s mail server. The “standard” reasons typically offered for a soft bounce are…
- Mailbox is full (over quota).
- The recipient email server is down or offline.
- The email message is too large.
What’s the average bounce rate for emails?I’ll save you trawling through for the number (but with a caveat…): 2019 email bounce rate benchmark: 1.05% Then, if you want to break it down by industry, you can use these figures as a basic reference: That caveat I mentioned? That number is an average and there’s a lot at play. The day you send your email, the time of day, the industry. All of these things can (and do) have an impact.
Tips for keeping your sales and marketing email bounce rate lowAs I said at the opener, I firmly believe that there are some differences between sales and marketing emails. So, by looking at them differently you can prioritize the things you can do to achieve your ideal bounce rate.
Reducing bounce rates for sales emails
Take care with bought email listsI’m not really into the whole sanctimonious, finger-wagging that many in this industry like to launch into when the subject of buying email lists comes up. It must be nice up there, with your thousands and thousands of organic leads. The reality for many others is that bought lists are an effective way of getting results, fast. But, caveat emptor. If you are going to buy an email list, make sure you run it through at least one email list cleaning service. This is so that you can avoid “spam trap” emails. These are addresses that, most of the time, have never been attached to a person and exist solely for the purpose of detecting spammers. When an email reaches this address, the recipient flags you as a spammer and blacklists your domain. Sometimes just within their organization, but the worst-case scenario is you get blacklisted at the IP level. Either way, it’s bad. So, make sure you’re cleaning those lists, and you’re more likely to achieve an acceptable email bounce rate.
Don’t send spam – or something that looks like spamSounds kinda obvious, right? It’s always worth asking yourself “would I open this email or click on the links?”. Chances are if you even have to think about it, your recipients are going to be far more judgemental. That is if you even reach them in the first place. If you consistently send spammy looking emails, spam filters – essentially gatekeepers of the email world – can flag you address or whole domain and just bounce your messages right back to you. Spend a little bit of time getting a third-party service to test your messages for spamminess. Or even better, avoid including potential spam triggers in the first place to maintain an ideal bounce rate.
Don’t send emails from a freebie serviceSending emails from, sales or marketing related, from a free email domain, like gmail.com or hotmail.com is a big no-no. Aside from the technical reasons, which I will come to in a second, even if your email doesn’t bounce, having a freebie domain looks kinda unprofessional. What’s more, in this day and age, using a custom domain really isn’t that hard. In my opinion, the absolute easiest way is:
- Purchase a suitable domain – Prices vary wildly, but you can start by paying only a few bucks for a domain to get started.
- Get a Google G-suite account via Google Domains – The advantage of buying G-suite via Google Domains is that it automatically sets up Gmail and email protection features. Neato!
Verify your domain (don’t worry, it’s not hard)Verifying your domain tells the receiving email server that, yes, you’re a legitimate sender and that you have permission to send emails from this domain. And according to one of the top sources of email marketing statistics, less than 40% of brands use three primary methods of email authentication: SPF, DKIM, and DMARC. Using domain authentication will improve email deliverability and reduce bounce rates. In order to set this up, you’d need to have your own custom domain in the first place (see above). Then, if you want a third-party email marketing tool like Outfunnel to be able to send emails using your custom domain, you’ll also want to verify your domain for each tool.
Get personalPersonalizing your emails has a dual benefit in that it’s more likely to get past spam filters and get opened. Firstly, email clients look for large batches of inbound messages with the exact same subject line. By adding some personalization to your subject line you’re able to reduce the chances of your message getting flagged as spam. Adding personalization to the subject line can increase unique open rates by 26% versus boilerplate subject lines, so once your email has reached their inbox, the recipient is more likely to actually open it. If you’re looking for some ideas to get your creativity flowing, here’s a solid list of 100 personalized email subject lines to get things going.

Use clean, simple codeChances are, even if you’re sending a plain-text looking email, if it includes images and links, it’s more likely to be “rich text”. This means your message contains HTML. Email clients and spam filters look at the contents of your message differently compared to human eyes. When the email lands in their inbox, it will look something like this:
Hi, I trust this email finds you well. I noticed you currently use Mailchimp to send your automated emails and wanted to ask whether you think you’re getting good value for money? If you’re just sending simple, rich text emails (like this very message), then Outfunnel can save you piles of cash each year. Let me know if you fancy saving a couple of hundred bucks a year. Thanks, Ben No longer interested? UnsubscribeThe properly formatted HTML should be clean and simple, like this: OK, yes there are some in-line styling elements here and there, but everything’s right where it should be. But you’ll run into problems if you start copying your content from one email marketing tool to another. Each platform usually adds its own styling or formatting elements, resulting in sketchy looking HTML, like this: And that awkward looking code is just as off-putting to spam filters as it is to human eyes. Adding lots of images can also result in bad HTML, so keep pics to a minimum. And if, like me, you prefer to draft your copy in Google Docs or Microsoft Word, clear any formatting after you paste the draft into your email marketing platform.
