When it comes to email marketing, Gmail deliverability is one of the most critical factors to ensure your messages reach your audience's inboxes. Gmail, with its sophisticated filtering systems and tabbed inbox experience, can make or break your email campaigns. To help you navigate these challenges, we’ve compiled a comprehensive guide on how to improve your Gmail deliverability, avoid the spam folder, and keep your subscribers engaged.
Why Gmail Deliverability Matters
Gmail accounts for a significant portion of email users worldwide, and getting your emails into the Primary inbox rather than the Promotions or Spam tabs can drastically improve your open rates and engagement. However, Gmail’s filters are highly sensitive to poor practices, and if you’re not careful, your emails could end up in the dreaded spam folder—or worse, blocked entirely.
To ensure your emails land where they should, here are some essential tips and best practices.
1. Stick to a Consistent IP Address
One of the most important factors in Gmail deliverability is the IP address from which you send your emails. Ideally, you should stick to the same IP address for all your communications. However, if you need to send from multiple IP addresses, make sure to designate distinct IPs for different types of messages. For example:
- Use one IP address for transactional emails (like account notifications).
- Use another IP address for promotional offers.
This separation helps Gmail categorize your emails correctly and prevents any confusion that could harm your deliverability.
2. Warm Up Your IP Address
If you’re using a new IP address, it’s crucial to warm it up before sending a high volume of emails. IP warming involves gradually increasing the number of emails you send over a period of weeks. This allows Gmail’s filters to recognize your IP as legitimate and trustworthy. If you skip this step and send a large volume of emails right away, you risk being flagged as spam or blocked entirely.
3. Avoid Mixing Content Types
Never mix different types of content in the same email. For example, don’t include a promotional message about an upcoming sale in a transactional email like a receipt or account update. Gmail’s filters are designed to detect these inconsistencies, and mixing content types can hurt your deliverability.
4. Regularly Check Your Domain’s Safety Status
Ensure that your domain (and any linked domains) aren’t flagged as unsafe. You can use the Google Safe Browsing tool to check the status of your domain. If your domain is flagged, Gmail may automatically send your emails to spam or block them entirely.
5. Keep Subscribers Engaged
Gmail actively prompts users to unsubscribe from promotional emails they haven’t interacted with in the last 30 days. To avoid this, it’s essential to keep your subscribers engaged through two-way communication. Avoid using no-reply emails, as they discourage interaction and hurt engagement. Additionally, regularly cleanse your email lists by removing inactive subscribers to maintain a healthy sender reputation.
6. Use Separate Email Addresses for Different Message Types
Gmail’s tabbed inbox organizes emails into categories like Primary, Promotions, and Social. To ensure your emails land in the correct tab, use separate email addresses for different types of messages. For example:
- Use one email address for transactional emails.
- Use another for promotional content.
This helps Gmail’s machine learning algorithms categorize your emails more accurately.
7. Authenticate Your Emails with SPF, DMARC, and DKIM
Email authentication is crucial for Gmail deliverability. Without proper authentication, your emails are more likely to be marked as spam or rejected. At a minimum, you should set up SPF, DMARC, and DKIM for your domain:
- SPF: Ensures that only authorized senders can send emails on behalf of your domain.
- DKIM: Adds a digital signature to your emails, verifying that they haven’t been tampered with.
- DMARC: Provides instructions on how to handle emails that fail SPF or DKIM checks.
These authentication protocols help build trust with Gmail and improve your deliverability.
8. Be Cautious with Links
The links you include in your emails can also affect deliverability. Gmail checks the reputation of all domains linked in your email, not just the sending domain. To improve deliverability:
- Use self-hosted links whenever possible.
- Avoid using link shorteners or third-party links, as they can raise red flags with Gmail’s filters.
9. Optimize Email Size and Content
While the size of your emails isn’t the most critical factor, it can still affect deliverability. Emails that contain very little text and are composed mostly of images (or one large image) are often flagged as spam. To avoid this:
- Ensure your emails have a good balance of text and images.
- Avoid sending emails that are just one large image with a link.
10. Create a Consistent Sending Pattern
Establishing a consistent sending pattern—whether daily, weekly, or monthly—helps build subscriber expectations and strengthens your visibility. Regularly sending emails at predictable intervals can improve engagement and reduce the likelihood of your emails being marked as spam

11. Monitor Response Data
The response data provided by your Email Service Provider (ESP) is one of the best tools for protecting your deliverability. Regularly check metrics like open rates, click-through rates, and bounce rates to identify any issues. We recommend reviewing your response data at least once a week and making adjustments as needed.
Official Gmail Guidelines for 2024
Starting in 2024, Gmail has updated its guidelines for sending emails to personal Gmail accounts. Here are some key points:
- Sender Authentication: All senders must set up SPF or DKIM, and bulk senders must set up SPF, DKIM, and DMARC.
- TLS Connection: Use a TLS connection for transmitting emails (effective Dec. 2023).
- Opt-in and Engagement: Only send emails to recipients who have opted in, and regularly confirm their interest.
- Unsubscribe Options: For senders of 5,000+ emails/day, support one-click unsubscribe by including the necessary headers.
