Hello, Whenever I try to send an email through Hubspot I get an error message on Outlook 365 which declares "Your message wasn't delivered because the recipient's email provider rejected it."How do I fix this?

Hi @IThompson6,

 

Could you confirm that you have connected your email sending domain and set up email authentification (SPF, DMARC)? Both are considered best practice and should help with your email deliverability and would be the first steps towards better deliverability.

 

In general, similar to SEO, you want to try to pass on as many positive signals about your content as possible. The eventual decision what to do with that content rests with the service provider. With that in mind, here is a list of things that I'd recommend reviewing:

 

Connect your email sending domain

Use a DMARC policy with HubSpot

Only email contacts who for whom you have a legal basis to communicate

Validate emails before sending to avoid hard bounces at all costs (e.g. Neverbounce, Zerobounce)

Remove unengaged contacts from list regularly for higher engagement rates

Avoid as many spam trigger words as possible

Test the spammyness of your email

 

@kaburke wrote an excellent email deliverability listicle and @natsumimori also compiled a lot of great resources here. I highly recommend you check out both. Over time, email service providers should recognize you as a trustworthy sender. The issue could be that in the past, some recipients have already marked your emails as spam or that email service providers noticed high bounce rates from you.

 

If you have already taken some of these steps or more context to share, let me know.

 

Best regards!

If you're experiencing issues with emails not being sent, there could be various reasons behind this problem. Here are some common troubleshooting steps you can take:

1. **Check Email Configuration:**
- Verify that your email client or server settings are configured correctly. Double-check the email address, server details, port numbers, and encryption settings.

2. **Check Spam Folder:**
- Sometimes, emails are marked as spam by email providers. Check the spam or junk folder in both the sender and recipient accounts.

3. **Review Outbox:**
- If you're using an email client, check the outbox for any emails that are stuck or failed to send. You may find error messages or details about why the emails couldn't be sent.

4. **Internet Connection:**
- Ensure that your internet connection is stable. A poor or intermittent connection could prevent emails from being sent.

5. **SMTP Server Issues:**
- If you're using an SMTP server, make sure it is operational and correctly configured. Check with your email provider for any known issues.

6. **Email Service Status:**
- Check if the email service provider is experiencing any outages or issues. Visit their status page or contact support for information.

7. **Attachments and File Size:**
- Large attachments or files may cause email sending issues. Check the file size limits imposed by your email provider.

8. **SMTP Authentication:**
- Ensure that your email client is set to use SMTP authentication if required by your email provider.

9. **Firewall/Antivirus Settings:**
- Your firewall or antivirus software may be blocking the outgoing email. Review the settings and temporarily disable them for testing purposes.

10. **Contact Email Provider Support:**
- If the issue persists, contact your email provider's support for assistance . They can provide specific guidance based on their system.

Remember to double-check all the details in your email client settings, and if you are using a web-based email service, check for any error messages that may indicate the cause of the problem. If the issue persists, contacting your email service provider's support is usually the best course of action.
