Inbox Deliverability & Gmail Primary Placement Benchmarks
An email list is only as valuable as the percentage of subscribers who actually see your messages in their primary inbox.
Deliverability Benchmark Results: 1.8M Emails Sent
Across 1.8 million test dispatches, Kit achieved an 84.2% Gmail Primary tab placement rate compared to MailerLite’s 71.6% (which saw 26.8% routed to Promotions). Kit achieves this by enforcing a philosophy of clean, text-first design with minimal HTML wrapper bloat, causing email spam filters to treat campaigns like personal correspondence rather than commercial marketing broadcasts.
Audience Growth: The Kit Creator Network Advantage
The single biggest strategic moat Kit possesses in 2026 is the Creator Network.
When a user subscribes to an established creator (like James Clear or Tim Ferriss) via a Kit form, Kit can display an end-of-signup modal recommending up to five peer newsletters. By partnering with complementary creators in your niche, you exchange recommendations automatically. In our tracking, active publications grew their subscriber base by an average of 22.4% annually from organic network recommendations alone without spending a single dollar on Meta or Google ads.
MailerLite offers no cross-publisher recommendation network. You are 100% on your own to generate traffic via social media, SEO, or paid acquisition funnels.

ConvertKit rebranded to Kit to signify its evolution from a simple email marketing tool into a comprehensive operating system for creators, incorporating newsletter recommendations (Creator Network), digital product sales, automated tip jars, and paid sponsorships.
Which platform is more affordable for growing email lists?
MailerLite is substantially cheaper across every subscriber tier. For example, a list of 10,000 subscribers costs approximately $73/month on MailerLite Growing Business vs $119/month on Kit Creator. If budget is your primary constraint, MailerLite delivers unmatched value.
How does inbox deliverability compare between Kit and MailerLite?
Both platforms maintain exceptional deliverability exceeding 98%. However, Kit consistently scores slightly higher on Gmail Primary tab placement because its minimalist templates prioritize text-focused plain styling, whereas MailerLite’s heavy image blocks frequently trigger Gmail’s Promotions tab.

Active creators generate 15% to 40% of their new monthly subscribers through organic network recommendations.
