My emails are going to the spam folder! Help!
Last updated on: June 22, 2023

This is never fun, and we sympathize with you. Using email for business is a challenge.

It’s hard because there are SO many spammers out there – nearly 55% of all email is spam! – and the inbox providers (Google, Yahoo, Microsoft, etc) too often throw out your “good” mail with the bad. Frustrating!

So, what can you do?

This document is meant to be a short-form answer to that question. We will skip all the technical explanations and drive right to the point.

How do inbox providers decide what to trash and what to keep?

Back to top

This is the question, right?

If you knew how they made that decision, you could make sure your email looks more like “good” mail and less like “bad” mail.

Well, fortunately, we DO know the answer!

There are 5 things that inbox providers use to determine where an email goes. We’ll call this your reputation chain.

  1. Email Content and Promoted Domains
  2. Historic Engagement Metrics
  3. “Send from” Address
  4. Return Path and Authentication
  5. IP Address

Together, these are the factors that inbox providers look at to determine whether your email should be inboxed or spamboxed.

At Ontraport we give every user, at every account level, access to professional-level tools to take responsibility for and manage your ENTIRE reputation chain.

What is my email reputation chain?

Back to top

As noted above, there are 5 factors that make up your personal reputation chain. Here they are described in more detail.

1. Content and Promoted Domains

This includes the words and links you put in the body of your email.

It’s pretty easy for inbox providers to decide that emails talking about losing weight and making money (for example) are likely spam. That makes it hard for legitimate folks in those industries (and others) to get good delivery, but that’s just the reality. Figure out ways to talk about your subject without suspicious language in your emails… and keep that stuff on your website instead.

Notably, the URLs that are promoted (linked to) in your email carry their own reputation. That means that if you send email that includes links which have, in the past, also been found in spammy emails, then the inbox providers will likely consider your email to be spammy also.

That’s why, for example, affiliate marketers can really have challenges because, if someone sends a lot of spam to promote your URL, other senders can also end up in the spam folder for promoting the same URL.

Tips: Here are some thoughts about the content of your emails that are worth looking at.

Also, don’t promote Ontraport domains (, etc.) or any other shared domains (, etc.) in your emails. Instead, use your own custom domain so all the links in your emails are to URLs that you alone control. This is an important part of owning your own reputation chain.

2. Historic Engagement Metrics

Your recipients’ histories of opening, reading and clicking your emails has a major impact on future delivery. To improve this, only send emails that people want to read to people who want to read it. Stop sending email to people who don’t engage, or at least mail those people much less frequently than the rest.

Tips: Use good list management practices. That means only using permission-based lead generation (never buy, rent or borrow a list!) and only sending high-quality, interesting content to people who actually want to get it. Stop sending emails to people who never engage. There are template autoamtion maps in the Ontraport marketplace that make it easy to stop sending to unengaged contacts automatically.

3. “Send from” Address

Don’t send from a freemail email address (gmail, yahoo, hotmail) or from a shared domain (ontramail). Instead, build your own good reputation by sending from a custom domain.

Tip: Just set it up here.

4. ReturnPath and Authentication

Better yet, set up your own custom Envelope Sending Domain (aka ReturnPath). This requires some more setup (SPF records, DKIM and, ideally, Dmarc) but pays off in the long run by, again, building your own mailing reputation and separating your delivery results from every other business that sends email on Ontraport.

Tip:Set up a custom domain and get at least SPF and DKIM setup. Dmarc is also an increasingly good idea, but you can take care of that later as it’s more technically complex.

Remember to warm your reputation if you send a significant volume of email (tens of thousands per month). Contact for more information about warming your reputation.

5. IP Address

You can use our shared IP addresses, which we monitor carefully, but getting your own IP address and building your own reputation is a great idea if you send on a regular, consistent basis and send at least 30k emails per month.

Tip: If you qualify, contact support to get the ball rolling on this. There is a one-time $500 setup fee for a private IP. Remember to warm your reputation if you send a significant volume. Note that if you don’t send a significant volume of mail, don’t worry about this. Shared IP addresses are fine for most users and are really one of the less important aspects of your personal reputation chain. Take this on only after you’ve done all the above and haven’t seen results you like. Click here for more details on how this works.

Frequently Asked Questions

Even my transactional emails are going to spam!

Back to top

The inbox providers can’t tell the difference between a transactional email and all the rest, so they look at your entire reputation chain, which includes ALL the email you send as a company, to determine what to do with each email.

This means that if you send a lot of email to folks who don’t want it, don’t read it, and don’t click it, you’re building a poor email reputation for your company, and that will impact your transactional email too.

What if none of this works?

Back to top

It will! It’s that simple!

If you’re still getting poor delivery results after taking care of all the above, you probably haven’t quite nailed down the above recommendations.

How do we know this? We know because there is NOTHING ELSE that an inbox provider can look at when deciding what to do with an email except the items above. If you have taken responsibility for each of those items, by owning and managing your own reputation chain, there is only one possibility: One of those items is not being well managed.

Most commonly, it’s the “Historic Engagement Metrics” piece.

Too many business owners continue to believe that they can just fire off a ton of emails to whomever they want and that the more they mail, the better… because some percentage of recipients have got to respond!

Unfortunately, that’s not how it works any more. The inbox providers have figured out that strategy and have put in safeguards to ensure that most or all of the email sent by companies deploying that strategy will end up in the spam folder.

In 2020 and beyond, the strategy is to only send high-quality emails to people who actually want to receive them.

Really, it’s Hotmail/MSN/ addresses that are the problem.

Back to top

We hear that.

Microsoft, and a few other providers like Cox, Comcast, etc., are way behind in email delivery technology, and they throw a LOT of good email into the bad pile.

This is an industry-wide problem that can be really hard to deal with.

Here are a few tips:

  • Use a conditional page redirect or conditional blocks on your page to warn recipients with Microsoft email addresses about the problem and how to look in their spam folders. (They probably already know, since this happens all the time to them, but still worth doing.)
  • Consider running a re-engagement automation ONLY to Microsoft addresses, and strictly limit the engagement window to 90 days, never emailing someone with no activity for longer than that. This will ensure you never hit a spam trap, which is a classic (and dumb) Microsoft technique for labeling spam.
  • Once you’ve got your own reputation chain set up, sign up for SNDS and monitor your results there. This will only work if you get your own IP address, but we monitor this for you if you’re using our shared IP address pool.

Additional email delivery services and strategy

Ontraport also offers the following additional services and strategies to further improve your delivery.

Strategy for managing low open rates

Back to top

ISPs are constantly trying to keep spam out of inboxes and, when they see messages that rarely get opened, it tells them that the message is unwanted. If you send your email to people you know will click on it before sending it to anyone else, it shows ISPs that the message isn’t spam and that it’s safe to deliver that message into other inboxes.

This strategy splits your contacts into groups based on their last activity so you can send your email to your most engaged contacts first, boosting the credibility of the email before sending it to your less engaged groups. 

Here’s how to utilize that strategy in your account:

  1. Create three groups in your account based on your contacts’ engagement with your content. Use the following conditions to create your groups:
    • “Last Activity is on or after 30 days ago” — Contacts who were active in the last 30 days
    • Last Activity is before 30 days ago AND Last Activity is on or after 90 days ago” — Contacts who were active 31-90 days ago
    • Last Activity is before 90 days ago” — Contacts who have not been active for over 90 days
  2. Start a re-engagement automation map for your contacts who have not been active in over 90 days.
    • After these contacts run through your re-engagement automation, remove all uninterested contacts from your mailing lists.
  3. Continue sending your usual emails to the contacts who have been active within the last 30 days.
  4. Send fewer messages to your less engaged contacts. Send emails to your contacts who were active in the last 31-90 days only once every third mailing.
    • On days that you are sending messages to your 31-90 day actives, we recommend that you:
      • Email your engaged contacts first (active in the last 30 days)
      • Email your 31-90 day actives two hours after emailing your engaged contacts. ISPs are more willing to treat your second send better when they see that your active group engaged with your first email.
  5. Implement a list re-engagement automation map to help ensure you’re only sending emails to people who want them which improves both your email stats and your deliverability. 

You can install the prebuilt “List Cleaning and Re-Engagement Automation” to create your own automation.

  • Click here to download your automation map.
  • Follow the instructions on your automation checklist to complete it.

It is important to note that ISPs will not change how they handle your mail overnight. This process can show some pretty noticeable results in as little as two weeks, but if your engagement issue has gone unaddressed for years it could take over a month to see noticeable changes.
