FAQ
Frequently asked questions
Everything you need to know before getting started.
What is a newsletter analytics dashboard?
A newsletter analytics dashboard gives marketers a single view of performance metrics, content scores, and competitive benchmarks across every newsletter they track. Newsletrix automatically scores subject lines, CTAs, readability, and sentiment for each send, and shows SWOT analysis, send-time heatmaps, and keyword trends side by side across all tracked competitors.
How do I check a newsletter for quality and spam issues?
Subscribe to any sender using your unique Newsletrix forwarding address. Newsletrix automatically checks every email that arrives - analyzing subject-line strength, content quality, readability, spam content signals, CTA placement, and link structure. Results appear in your dashboard within minutes of delivery.
Does Newsletrix include an ESP checker?
Yes. Newsletrix detects the email service provider (ESP) - such as Mailchimp, Klaviyo, SendGrid, or Beehiiv - for every newsletter analyzed. ESP detection runs automatically alongside content scoring and SWOT analysis with no extra steps required.
Does Newsletrix run a newsletter spam test?
Yes. Every newsletter analyzed by Newsletrix receives an automatic spam content score checking for spam-triggering language, excessive link density, and deliverability risk factors in the email body. This check runs on every send automatically.
Do I need to install anything?
No. You get a unique forwarding address - subscribe to any newsletter with it, and Newsletrix handles the rest. Zero integrations required.
Which newsletter platforms do you support?
Any platform that sends email - Substack, Beehiiv, Mailchimp, ConvertKit, Klaviyo, custom in-house tools. If it lands in an inbox, we analyze it.
Is there a free plan?
Yes. The free plan includes every feature, 2 analyses per week, and 1 tracking address - no credit card needed.
Can I cancel anytime?
Yes. All plans are month-to-month. Cancel from your dashboard with one click - no contracts, no calls.
How fresh are the insights?
Every newsletter is analyzed within minutes of arriving. Trends, recommendations, and SWOTs update automatically as new sends come in.
Is my data private?
Your tracked newsletters and insights are yours alone. We don't share your data with other customers, and you can export or delete it at any time.
