Imagine this scenario — you’re a sender that is sending massive amounts of email left and right from the same domain without a care in the world about reputation. I bet you would feel like all that email will help warm your IP, right? Get yourself a good reputation with ISPs?

No. Stop that.

Now we understand that a lot of times, senders might not know that this can cause problems for their reputation. This is one of those things that a lot of senders learn with time and sometimes with trial and error. Your reputation is based on a variety of factors, but the emails you’re sending are a big determining factor. Not all emails serve the same purpose, and that means that they affect your reputation in different ways. Before we get into that, let’s define the emails that affect your reputation the most — Marketing Emails and Transactional Emails.


Marketing emails – your brand megaphone

Marketing emails are one of the best ways to get news about your product and services to new or loyal subscribers. The cut and dry definition: marketing emails are solicitations sent to email addresses that have opted-in to receive them. Marketing emails are anything like newsletters, sales promotions, blog updates, third-party offers, promotional invitations — anything that might land in the Promotions tab of your Gmail inbox if you have those tabs enabled.

When done right, marketing emails are one of the best ways to retain customers and bring a great ROI for your business. It’s an invaluable part of any marketing strategy, so making sure you’re up to best practices is imperative. Not following best practice can lead to problems, but before we get into that — let’s talk about transactional emails.


Transactional email – your service helper

Everybody knows transactional email in some way, shape, or form. Transactional emails are those triggered, one-to-one messages sent to users after they interact with a company, website, or application in some way. They often contain information that the user requested and would want on file, so it’s best to have those emails automated. Good examples of this would be password resets, receipts, order confirmations, shipping alerts, feedback surveys, ToS updates, and a variety of other notifications.

A lot of people expect to get these emails anyway, and they often want them right after the event is triggered. You definitely don’t want your transactional email running into slow send times or a total lack of notifications at all. Like marketing emails, a lot of transactional emails succeed when best practices are followed.


Reputation battle

Marketing and transactional emails are all just emails, but how people perceive them is very different. Some users might not be the biggest fans of marketing emails so sentiment can be shaky from time to time. When marketing emails are performing well, your sending reputation is too. However, if your marketing emails are getting low engagements, your reputation can take a hit.

Transaction-based emails, on the other hand, tend to have very high engagement rates. Why? The emails themselves have information that many users need, so people are more likely to open those emails. Like we said earlier, transactional emails are sent when a user makes a request and are a bit more technical, so the nature of the email lends itself to higher engagements.

TL;DR — Transactional emails tend to bring you a higher reputation than marketing emails.

When you have emails that might have a lower reputation paired with emails that lend themselves to higher reputation, things can get messy. If your reputation is taking a particularly bad hit, things like password resets and receipts can end up in spam. Transactional emails in spam lead to unhappy customers, and those makes more work for you to solve the problem.


The solution – subdomains

If you find yourself sitting here going, “Oh crap, this is happening to me!” Don’t freak out too much. This problem can be fixed with subdomains. Using subdomains for your marketing and transactional emails allows you to separate those domain reputations. That separation ensure that they don’t affect each other and end up causing problems should something go haywire with either. Great examples of this would be subdomains like marketing.domain.com or promotions.domain.com for marketing emails and receipts.domain.com or transactions.domain.com for transactional emails.

Now there are some finer details to subdomains you should know before separating your marketing and your transactional emails. For one, subdomains are best suited to high volume sending. If you aren’t sending tons of email, it’s best to have just one domain to start with to help start a reputation for your brand. The same can be said for IPs; if you have massive amounts of emails to send, think about separating your IPs to help control your IP reputation.

Second: don’t use something like (code text: donotreply.domain.com)! We see this a lot with senders, and it breaks our hearts because you’re taking out the best engagement – replies! If you have a “do not reply” subdomain setup, create a new one that doesn’t deter customer interaction. If you’re worried about figuring out what to do with all the inbound messages you’ll get, we can help with that.



In an ideal world, all of your emails would have high open and engagement rates across the board. Unfortunately, that is not likely to be the case. By no means should you get rid of either type of email altogether… you’d be throwing away some of the best customer satisfaction and service tools out there. However, keeping your marketing and transactional emails separated will help you avoid getting a super sassy complaint on social media about how an email receipt ended up in spam.
