What it is

DayClerk turns a campaign brief into audience-specific marketing materials. It simulates audience behavior, then creates landing-page variants, email copy, social posts and ad copy. The Landing Page Wizard includes an inline editor, and pages can be published to a live URL. Email Architect generates a segment-specific email with a subject line, preview text, body and CTA, downloadable as HTML. Social Studio produces copy for six platforms per segment, while the Activation Guide gives channel and timing recommendations in a downloadable PDF. DayClerk does not schedule posts, manage ad campaigns, send emails or run A/B tests: users send email through their own tool and paste social copy into platforms. It runs on the web. Explorer is free to build, but publishing each campaign costs $29.98; Growth Engine is $29.00 per month, Pro is $59.00 per month, and Agency is $149.00 per month. Mailchimp syncs newsletter subscribers with tag-based segmentation, and Pro and Agency can connect Google Analytics 4.
