Did you know that nearly 20% of marketing emails never reach the inbox? Even if you’re using HubSpot, your emails can still end up in the spam folder.
This can hurt your open rates, click-through rates, and even your business reputation. Email providers use strict filters, and a few small mistakes can trigger them.
If you’re seeing low engagement or your contacts say they didn’t get your message, spam filters might be the reason.
Let’s look at what causes this and how to fix your HubSpot email deliverability step by step.
Key Takeaways
HubSpot Email deliverability means whether your email reaches someone’s inbox or gets blocked or sent to spam. In HubSpot, this depends on how you send your emails, who you’re sending them to, and how they react. If people often delete your emails without reading or mark them as spam, your sender score drops.
HubSpot tracks your open rates, bounces, and complaints to see how healthy your email list is. A good deliverability rate means more people see your emails. A bad one means your emails may go unseen, even if everything else looks right.
Spam filters check every email before it reaches someone’s inbox. They look for signs of spam, like bad links, strange wording, or unknown senders. If your email checks too many boxes, it goes straight to spam.
Here are some common reasons this happens in HubSpot:
Even if you have a great message, some mistakes can hurt your chances of landing in the inbox. Here are the most common errors HubSpot users make that lower email deliverability:
Good email deliverability means your emails go to the inbox, not the spam folder. Here’s how you can boost your results in HubSpot:
SPF and DKIM are like ID checks for your emails. They show email services that your messages are real. Set these up through your domain settings to build trust.
Don’t send marketing emails from Gmail or Yahoo. Use your business domain and connect it in HubSpot. This shows you’re a real sender.
Remove old, fake, or inactive contacts. This helps lower bounce rates and keeps your list healthy. Only send to people who want to hear from you.
Double opt-in asks contacts to confirm their email before they’re added to your list. This makes sure your contacts are real and interesting.
Not every email fits everyone. Create groups based on interests, behavior, or location. Send the right message to the right group to get better results.
Try different subject lines and email styles. See what gets more opens and clicks. HubSpot makes testing easy, so you can improve with each send.
Use HubSpot analytics to track opens, clicks, bounces, and unsubscribes. These numbers show what’s working and what needs to change.
Spam filters look for warning signs before letting emails through. Here’s how to avoid those traps in your HubSpot campaigns:
Link only to reputable sites: Spam filters check the links in your emails. Make sure your links go to trusted, well-known websites. Avoid broken or suspicious URLs.
If your emails keep going to spam, try these steps to fix the problem:
Contact HubSpot support if problems persist: If you’ve tried everything but your emails still go to spam, reach out to HubSpot’s support team. They can help spot technical issues and guide you to a solution.
