Frequently Asked Questions
Common questions about Letterness: Newsletter Plugin, Popup & Email Marketing
Yes. Every feature described here is free: signup forms, unlimited subscribers stored in your own database, newsletter sending, automations and reports. There is no per-subscriber pricing.
No. Letterness stores subscribers in your own WordPress database and sends through wp_mail(). For higher deliverability on larger lists we recommend a free SMTP plugin such as WP Mail SMTP or FluentSMTP, which Letterness works with automatically.
Yes. Upload a CSV, map the columns, choose a list and review the preview. Letterness skips duplicates, flags invalid addresses and runs the import in steps so large files do not time out. You will be asked to confirm that you have permission to email the people you import.
Yes. Pick one or more lists, then narrow the audience with tag, language and custom field rules. A recipient count shows how many people will receive the campaign before you send.
Yes. Turn on the welcome automation and choose to send immediately or after a delay in minutes, hours or days.
Yes. New-post notifications can send instantly on publish or collect posts into a scheduled daily or weekly digest, filtered by post type and category.
Yes. Paste one or several article links and Letterness builds an editable article block for each, with the title, featured image and summary. You can also pull recent items from an RSS or Atom feed.
Yes, with the subscriber's consent. Each campaign shows opens, clicks, unique counts, rates and the most-clicked links, and subscribers can choose no tracking, anonymous totals, or individual tracking. Open tracking is approximate, since many email apps block or preload images. Click tracking is exact.
Every email has a visible, signed one-click unsubscribe link and standards-based List-Unsubscribe headers, so inbox providers can show a native unsubscribe button. A secure preference link also lets subscribers update their details and lists. Unsubscribing shows a confirmation page and immediately suppresses the address.
Letterness includes an optional consent checkbox with your own wording and privacy policy link, records the consent text with each signup, supports double opt-in, and never sells or shares data. Analytics store a one-way hash of the email rather than the address itself. You remain responsible for your own compliance, so check the rules that apply to you.
