15 Email Deliverability Best Practices For Gmail

Key Takeaways

    • Premise: Gmail’s ecosystem is uniquely strict. With 1.8B+ users and advanced filtering systems, deliverability depends on sender reputation, subscriber engagement, and technical configuration.

    • Goal: Provide a clear framework for avoiding Gmail-specific deliverability issues before they happen.

    • Highlights:

      1. Gmail’s Reputation System Is Multi-Layered

        • Gmail analyzes engagement, complaints, list quality, sending domain/subdomain, DKIM, SPF, IP reputation, bounce patterns, content, coding, and more.

        • Because signals are aggregated across domain + subdomain + IP, troubleshooting becomes difficult if fundamentals aren’t set early.

      2. Opt-In Quality Determines Everything

        • Gmail strongly prefers confirmed/double opt-in, but at minimum requires explicit single opt-in.

        • Users must opt into the exact message stream—not a category or parent-brand by association.

      3. Engagement Is Gmail’s #1 Currency

        • Send only to subscribers who open/click regularly.

        • Define expiry thresholds:

          • Daily senders → expect activity at least once every 30 days.

          • Weekly senders → at least once every 90 days.

          • No engagement for 12+ months → remove permanently (high spam-trap risk).

      4. List Health Matters More Than List Size

        • Stop sending to hard bounces.

        • Never purchase lists.

        • Build your own subscriber base through permission-based growth.

      5. Respectful Email Etiquette Improves Inbox Placement

        • Clear sender identity.

        • Accurate subject lines.

        • Transparent link destinations.

      6. Transactional vs Marketing Separation Is Crucial

        • Don’t mix marketing content into process-critical emails.

        • When possible, split streams using separate subdomains or IPs so transactional mail maintains a pristine reputation.

      7. Always Monitor Blacklists

        • Gmail uses third-party blacklists (undisclosed), so monitoring becomes preventive protection.

      8. Don’t Use URL Shorteners

        • Gmail distrusts them in bulk mailings—especially bit.ly.

      9. Make Unsubscribing Easy

        • One-click unsubscribe reduces spam complaints (Gmail doesn’t provide standard FBLs).

      10. Avoid Affiliate Links Entirely

        • Historically abused → triggers spam filters.

        • Also disallowed on SparkPost.

      11. Authenticate Fully (SPF + DKIM)

        • Required to establish domain reputation and pass Gmail’s authenticity checks.

      12. Build a Clean Technical Foundation

        • Correct PTR/rDNS.

        • Standards-compliant HTML and international formatting.

        • No obfuscated code.

      13. Warm-Up = More Than IP Volume

        • Gmail ties reputation to the entire DNS configuration, not just the IP.

        • Lock your setup before sending: SPF, DKIM, domain structure, subdomains, IP.

        • Any post-warmup changes → triggers another warmup cycle.

      14. Warm Up Based on Engagement Layers

        • Start with your most active subscribers → slowly expand outward.

      15. Understand Promotions vs Primary Tabs

        • Promotions tab is not spam—it’s a legitimate, high-performing surface.

        • Tab placement varies per user, not across your whole audience.

        • If needed, you can craft emails that look more “personal” to increase Primary placement:

          • Text-heavy

          • Minimal images

          • Only one link

          • Conversational tone

        • But overall: appreciate the Promotions tab—it often improves visibility, not hurts it.

Q&A Highlights

  • Why is Gmail harder than other inbox providers?

    Gmail evaluates more signals (engagement, domain behavior, content, coding, DNS configuration, blacklist status) and applies them at a user-specific level. It rewards high quality and punishes inconsistencies quickly.

  • What’s the single biggest deliverability driver for Gmail?

    Engagement. Highly engaged users → inbox. Low engagement → promotions or spam.

  • Why is double opt-in recommended?

    It ensures clean lists, reduces spam complaints, and prevents Gmail from lowering your domain reputation.

  • Should I worry about the Promotions tab?

    No. It’s visible, frequently checked, and preferred for marketing messages. You only need Primary placement when sending highly personal or non-promotional content.

  • How does Gmail handle unsubscribes and complaints?

    Gmail does not provide traditional feedback loops. That means unsubscribes are safer than spam complaints—make unsubscribing effortless.

  • Can I use affiliate links if they’re relevant?

    No. Gmail associates them with historically abusive senders, which can tank your reputation.

  • Why is URL shortening blocked?

    Many spammers use shortened URLs to hide malicious destinations. Gmail treats them as high-risk indicators.

  • How important is technical setup for Gmail?

    Extremely. A poor DNS configuration or inconsistent authentication breaks reputation alignment and makes warmups fail.

The top 15 email deliverability best practices you should follow in order to avoid issues to begin with when sending to Gmail.

With over 1.8 billion users, there is no debate that Gmail is a leader among email providers. Chances are you have many subscribers on your business lists with Gmail addresses, and increasing your chances of successfully reaching them is essential to your company. Understanding the filters and criteria Gmail uses to determine email validity will create improved deliverability for your communications.

Gmail uses many different algorithms to determine inbox placement as well as delivery of your messages. Those algorithms use countless points of reference such as engagement, complaints, bad addresses for a combination of sending subdomain and top domain, bounce domain and DKIM, IP address, body content, branding, source coding, etc. Therefore when you have an issue, troubleshooting can be overwhelming. For organizations in regulatory environments, these deliverability concerns extend beyond basic inbox placement to include comprehensive email archiving system challenges for compliance and auditing purposes.

1. Secure the Opt-in

Encourage your users to opt-in to your communications instead of checking these boxes by default. Some international regions restrict auto opt-in practices and levy fines or penalties for infractions. Keep your business compliant and do away with opt-ins by default.

Gmail strongly suggests double opt-in or confirmed opt-in when possible. However, single opt-in is a must. It is important that each subscriber opt-in to the exact message stream they are receiving. It is not enough that they opt-in for your type of message. For example: Katie opts-in to receive messages sent by JobSiteA. This does NOT mean that JobSiteB can start sending Katie messages simply because it is the same subject matter or even owned by the same parent company of JobSiteA. Katie has to explicitly opt-in to JobSiteB’s messages.

2. Track Engagement

The most important thing to remember is to send messages to subscribers who are engaged with your brand. They are opening, reading, clicking and interacting with your brand. This is especially critical for FinTech companies during the onboarding process, where building trust and engagement requires specialized strategies covered in our FinTech email onboarding optimization guide. Interacting may mean purchasing or even getting involved with the discussion depending on your business model. Develop a list hygiene process to remove nonengaged subscribers from your active sending list on a regular basis.

3. Keep Your Subscriber List Healthy

Do not continue to send to email addresses that no longer exist or hard bounce (SparkPost suppresses hard bounces). Do not continue to send to subscribers who have not opened or clicked in a reasonable time. This length of time really depends on your business model. A good rule of thumb is that actively engaged subscribers will open and/or click on your daily messages at least once in a 30 day time frame and at least once on your weekly messages within 90 days. Any subscriber that has not opened or clicked on your messages in the past 12 months should be permanently removed from your list as they run the risk of becoming a spam trap.

Build your subscriber list on your own rather than purchasing an email list from a third-party list vendor. Sending emails to users who haven’t requested them can generate spam complaints and cause potential harm to your sending reputation and deliverability.

4. Practice Good Etiquette

Being polite and professional helps create a positive impression for your business and increases Gmail deliverability. Your business name and purpose should be clear as the sender. Google also recommends email subject lines relevant to message content and links whose purpose and destinations are clear and pertinent.

5. Segregate Your Email Content

While many businesses use transactional emails as an extra promotional tool by recommending additional products, your deliverability to Gmail accounts increases if you keep marketing content out of process communications. If you employ more than one IP address, you can separate the two types of emails by IP to ensure transactional emails maintain a high sender reputation and prevent them from the spam label.

8. Use the Unsubscribe Features

Make it easy for subscribers to unsubscribe from your message! Google’s one-click feature permits users to click the unsubscribe button inside the email to simplify the process and prevent a user complaint. Spam complaints are not shared back to you through feedback loops like other ISPs. Therefore it is crucial that your subscribers unsubscribe rather than reporting as spam. SparkPost deploys the list-unsubscribe header and suppresses unsubscribes.

9. Avoid Affiliate Marketing Links

Affiliate marketers — those who earn commissions by directing web traffic to specific sites — have been known for spamming in the past. Establishing an identification as a spam sender can affect the deliverability of all future communications from your business. For best performance, Gmail states you should avoid including affiliate marketing links as a tactic. It is also against SparkPost policy to send affiliate marketing through our system.

10. Authenticate Your Emails

Authenticate with both SPF and DKIM.

11. Use Subdomains Wisely

Google suggests using a single IP address for all your email sending to aggregate the sender’s reputation under one label. When separating communication types with subdomains, ensure they all point to the same IP if possible.

Different subdomains can define your different email streams. (Example: newsletter.example.com; deals.example.com; confirmation.example.com) Be consistent. Don’t add too many as you want to be able to develop a reputation for each subdomain. However, remember that the top level domain reputation is also important.

12. Get Technical

Make sure your pointer (PTR) or reverse DNS (rDNS) records are up-to-date and correct. Adhere to standard message, HTML and international domain formats. Keep coding clean and transparent — concealing code could result in Gmail categorizing your email as spam.

13. Execute a Configuration Warm-up

In general, warming up IPs or domains when there is a change are what marketers focus on. However, Gmail ties reputation to the entire DNS configuration during warmup. The reputation is tied to the collective SPF, DKIM, IP setup, domain, ect., therefore it is imperative that you have your configuration set and locked in before you start sending. Once it is complete and verified by testing do not make any changes unless you are prepared to do another warmup for the new configuration. In the chart below, we provide some best practice warm up guidelines as you introduce your traffic into the GMAIL network:

15. Research Promotions vs. Primary Tabs

Due to the introduction of folders, subscriber traffic can now be delivered to additional locations and not solely the inbox or spam folder. It is not like the scary wasteland of lost messages called the SPAM folder. If you have an interesting subject line and a brand that your subscribers want to engage with, the promotions tab will still get you opens and clicks.

  • Per-user filtering. Remember that just because some subscriber messages may be in the promotions tab does not mean that all subscriber messages are in the promotions tab. Filtering is done on the individual subscriber level not bulk sender level.

  • HTML to Text Balance. Keep the balance of HTML to text similar.

  • Encourage Interaction. Subscriber awareness is important. Train your subscribers to expect the message and move the message into the Primary tab. The messages should start going to the Primary tab after a few moves.

  • Don’t send a promotion. When the above fails and you need a message to get into the inbox design your message to NOT look like a promotion.

    • Personalize your messages. Include the reader’s first name in your message to Gmail subscribers.

    • Lose the images. Gmail sees images as a sign of a promotion or spam message. You will increase your readership by not having pictures.

    • Use letter format. Design the Gmail template to look more personal and natural like an email.

    • Don’t include obvious calls-to-action. The best way to keep from looking like a promotion is to have no more than 1 link and no upsells or RSS Feeds. Keep it short and simple like talking to a friend.

  • Appreciate the promotions tab. When it comes down to it, if a subscriber wants your message in the primary tab they can move it there and will receive it there after a few moves. However, Gmail’s tabs are not new and subscribers know how they work and often go to that tab for promotions they are interested in. The promotions tab can actually work in your favor. For example, if a subscriber is very involved in social media and receives a large volume of social media notifications, marketing messages can get lost in the inbox and separating them out to the social tab can actually be a plus, which leaves your message to be seen at the top of the promotions tab easily found by your engaged subscriber. Just remember that if you send your subscribers what they want and leave them wanting more they will go to that promotions tab to see what you have to say!
