How To Land Into Gmail’s Inbox

Kristen Wyatt on July 31, 2023

Landing in Gmail’s primary inbox can be pivotal for email marketers and anyone sending important emails. Gmail’s inbox sorting algorithm automatically categorizes incoming emails into different tabs: 

  • Primary: Personal emails and messages from other categories where the tab isn’t turned on.
  • Social: Notifications and updates from social platforms.
  • Promotions: Promotional mail and other offers from email marketing and similar campaigns.
  • Updates: Transactional emails such as receipts and shipping notifications.
  • Forums: Mailing lists and groups.

To increase the likelihood of your emails landing in the Primary tab, follow these best practices:

Use a recognizable “From” name: Ensure your sender name is clear and recognizable. This helps recipients know who you are and why they are receiving your mail. Avoid using spammy or misleading names.

Use sub-domains: Create subdomains for each type of mail that you send (marketing, updates, transactional mail, etc). This will keep your top domain’s reputation safe. It also allows you a more detailed view of open/click tracking.  

Authenticate your domain: Implement Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) protocols to improve your email’s credibility and reduce the chances of being marked as spam.

Use a reputable email service provider: Use a reliable and well-known email service provider that actively manages its reputation to ensure high deliverability rates.

Send relevant and engaging content: Create valuable, personalized, and engaging content that recipients are more likely to interact with. Avoid using spammy language or excessive promotional material.

Avoid spam trigger words: Refrain from using common spam trigger words in your subject linked and email content, such as 

  • Free 
  • Discount
  • Limited time
  • Satisfaction guaranteed
  • No obligation 

Limit the use of attachments and large images: Emails with large attachments or image-heavy content might be considered suspicious and end up in the Promotions tab.

Avoid excessive use of links: Too many links inside your email can make it look spammy. Use links sparingly and make sure they point to reputable websites.

Maintain a clean email list: Regularly clean your email list to remove inactive or unengaged subscribers. Sending emails to unresponsive addresses may increase the chances of your emails being marked as spam.

Encourage recipients to move your emails: Include a call-to-action in your emails, asking recipients to move your emails to the Primary tab if they find them there. For example, ask them to drag and drop your email from the Promotions tab to the Primary tab.

Request adding your email address to contacts: Encourage subscribers to add your sending address to their contacts list. This action signals Gmail that the user considers your email as important.

Monitor and adjust your email strategy: Pay attention to your email open rates, click-through rates, and spam reports. Consider utilizing Google Postmaster Tools to gain more detailed insight into how Google views your sending domain(s). Adjust your email strategy based on the data to improve engagement and reduce spam complaints.

Remember, getting into the Primary inbox is not entirely within your control. Gmail’s algorithms are dynamic and always subject to updates. However, following these best practices should help improve your chances of landing there. Also, make sure that you comply with Gmail’s guidelines and policies to maintain a positive sender reputation.

IP Warming: What You Need To Know

Kristen Wyatt on July 7, 2023

IP Warming is the process of systematically adding email volume to a new IP address at a gradual pace in order to establish a positive sending reputation with Mailbox Providers. Sending activity from a new IP address can seem suspicious. Depending on the size of your sending list, warming can take an average of four to eight weeks. Warming could also take longer if providers do not perceive your mail is “wanted” by recipients. Some providers limit senders to specific thresholds until a stable reputation is established. 

Inbox Rev recommends starting off with your best-performing campaigns. You should focus on warming your most engaged subscribers while adding older segments as you progress. Older components should be added in bundles of 15% of your existing volume. The goal is to send to subscribers who are least likely to complain or bounce. This will include those who opted-in most recently and are consistently opening your mail and clicking. During your warmup phase, the more consistent you are with volume, frequency, complaints, and bounce levels, the faster you will establish a positive sending reputation.

An example of an IP warming outline would look something like this: During the first two weeks, send campaigns to your MOST ACTIVE subscribers – those who have opened/clicked in the past thirty days. During the next two weeks, extend to the subscribers who opened/clicked in the past sixty days. Follow this pattern until you have incorporated your entire sending list. During the first six weeks, DO NOT send to subscribers who have not opened or clicked in the last ninety days. 

Furthermore, once you begin warming your IP, you can expect some bulking and blocking to occur. Bulking at Yahoo!, AOL, and Gmail typically clear up after a few campaigns are sent with positive metrics. Delays at AOL, Comcast, and Microsoft (“421” Bounces) will typically retry for seventy-two hours. These delays are normal and will diminish as your reputation develops. However, if they are timing out in large quantities, you should back down your volumes to that provider by tightening up your engagement metrics. 

Possible blocking can also occur if your list isn’t engaged enough. Segment carefully and tighten up engagement. It is important to monitor your metrics and adjust the plan accordingly. Remember that engagement and consistency are key to a successful IP warm-up.
