Letterly is an AI-powered tool that transforms your newsletter content into engaging social media posts for LinkedIn and X (Twitter). It automatically repurposes your newsletter, maintains your writing style, schedules posts, and provides comprehensive analytics - all in one platform.

How does Letterly work?

Letterly works in three simple steps: 1) You paste your newsletter URL or content, 2) Our AI transforms it into platform-optimized posts while cloning your writing style or any creator's voice you choose, 3) Posts are automatically scheduled and published to LinkedIn and X at optimal times. You can review and edit everything before it goes live.

What platforms does Letterly support?

Letterly currently supports LinkedIn and X (Twitter) for direct posting and scheduling. For newsletter sources, we support Substack, Beehiiv, ConvertKit, Ghost, Mailchimp, and any other platform - you can simply paste a URL or copy-paste your content.

How much does Letterly cost?

Letterly offers a free trial with limited conversions. Paid plans start with flexible pricing options designed for newsletter creators of all sizes. Visit our pricing page for detailed plan comparisons and features included in each tier.

Can I try Letterly for free?

Yes! Letterly offers a free trial that lets you test all core features including AI content transformation, voice cloning, and scheduling. No credit card required to start. You can convert your first newsletter to social content and see the results before committing to a paid plan.

Can Letterly clone my writing style?

Absolutely. Letterly's AI persona feature analyzes your existing LinkedIn or X posts to understand your tone, vocabulary, emoji usage, formality level, and sentence structure. It then replicates this style when creating new content from your newsletters, ensuring everything sounds authentically like you.

Does Letterly support automatic posting?

Yes! Letterly can automatically publish posts directly to LinkedIn and X (Twitter) at scheduled times. Our Copilot feature can even generate and schedule an entire week's worth of content automatically, requiring minimal intervention from you.

What analytics does Letterly provide?

Letterly provides comprehensive analytics including: newsletter subscriber growth and open rates, social media impressions and engagement metrics, follower growth tracking across platforms, CTA click tracking with branded short links, post performance comparisons, and growth trend visualizations. All metrics are unified in a single dashboard.
