Quick Answer
How can you help prevent your emails from going to spam?
Use a dedicated sending domain, configure SPF, DKIM, and DMARC, include an unsubscribe link, keep your contact list clean, send to engaged contacts, and avoid email content and sending patterns that can damage your sender reputation.
Why Emails Go to Spam
You may be sending useful emails, but if they land in spam folders, your message may never reach the contact.
Inbox placement is influenced by sender reputation, email authentication, including SPF, DKIM, and DMARC, and engagement signals such as opens, replies, clicks, and spam complaints.
Your domain setup, list quality, and the way your emails are written and sent all contribute to those signals. Without the right setup and sending practices, even well-written emails can be filtered before they are seen.
The practices in this guide are designed to help protect your sending reputation and improve the chances that legitimate messages reach the inbox.
Email Deliverability at a Glance
Before You Begin
Email deliverability is affected by more than the wording of a single message. Review the foundation of your email sending setup before focusing only on email copy.
- Know which domain is being used to send your email.
- Make sure your sending domain is properly authenticated.
- Review the quality and engagement of your contact list.
- Make sure recipients have a clear way to unsubscribe.
- Consider how frequently you are sending and whether contacts expect to hear from you.
Best Practices for Better Email Deliverability
Use these practices together to protect your sender reputation, improve engagement, and reduce the likelihood of legitimate messages being filtered as spam.
Use a Dedicated Sending Domain
Use a domain specifically for email sending so you can build and protect its sending reputation separately from your main website domain.
Match Your From Identity
Use a consistent From name and email address that align with your brand and sending domain. Consistency makes it easier for contacts and mailbox providers to recognize your email.
Always Include an Unsubscribe Link
Give recipients a clear way to stop receiving email. Unsubscribe links can reduce spam complaints, support compliance, and help keep your list healthy.
Authenticate Your Domain
Configure SPF, DKIM, and DMARC. Authentication helps mailbox providers verify legitimate messages and can help protect your domain against spoofing and filtering problems.
Keep Your List Clean
Regularly remove bounced addresses and contacts who remain cold or unengaged. A cleaner list helps protect engagement signals and your long-term sending reputation.
Send to Engaged Contacts First
When warming a new sending domain, begin with contacts who are more likely to open, reply, or otherwise engage with your messages.
Avoid Spammy Content Patterns
Too many links, all-caps subject lines, aggressive hype, and other questionable content patterns can work against your deliverability.
Protect Forms from Fake Signups
When available, use protections such as double opt-in or anti-spam tools like reCAPTCHA to reduce fake and low-quality signups entering your email list.
Be Careful with Internal Testing
Heavy testing to internal inboxes can trigger security, spoofing, or spam flags. Use dedicated test addresses or deliverability testing tools when appropriate.
Set expectations with subscribers
If you send newsletters or recurring emails, tell subscribers approximately how often they should expect to hear from you and make it clear that they can unsubscribe.
Spam Trigger Words to Avoid
Spam filters evaluate overall sending and content patterns, but certain types of wording can still become risky when combined with excessive links, aggressive subject lines, or other poor sending practices.
Overpromises
Be careful with phrases such as “Guaranteed,” “Risk-free,” and “100% free.”
Urgency Hype
Avoid relying heavily on phrases such as “Act now,” “Limited time,” and “Final notice.”
Prize Bait
Be cautious with wording such as “Winner,” “Claim your prize,” and “Congratulations.”
Use clear wording instead of manufactured urgency
Write helpful copy that accurately matches the content of your email. When urgency is legitimate, explain the specific reason, such as a real deadline, schedule, or availability constraint, instead of relying on hype.
