Lumafly builds AI ad and content tools for growth teams. These free marketing tools solve common campaign headaches: emails that land in spam, links you cannot attribute in analytics, captions that exceed platform limits, scripts that run too long, and previews that look wrong after publishing.
Use them before you send a cold outreach batch, publish a newsletter, or launch a paid campaign. Every free tool runs in your browser or fetches public page metadata on demand, so you can check copy, URLs, SEO snippets, and social previews without installing anything.
Use the free email spam checker before sending newsletters, cold emails, sales follow-ups, webinar invites, and launch announcements. It flags risky words and formatting so you can rewrite copy before deliverability problems show up.
Use the free UTM builder to create Google Analytics campaign URLs for paid ads, creator campaigns, partner posts, email newsletters, QR codes, and social bios. Clean parameters make channel reports easier to trust.
Use free Instagram, TikTok, and X character counters to stay inside caption and post limits. Check the hook, hashtags, mentions, and preview cutoff before scheduling or handing copy to a creator.
Use the free SERP preview tool and social preview checker to inspect search snippets, meta descriptions, Open Graph cards, and shared-link previews before traffic starts arriving.
Small campaign mistakes compound quickly. A missing UTM parameter can hide the source of a winning ad. A weak meta title can make a useful page look vague in search. A caption that buries the hook can reduce clicks, and an email packed with spam trigger language can make outreach harder than it needs to be.
These tools are designed for the quality-control step that happens right before publishing. Paste the copy, URL, script, caption, or page metadata, make the obvious fixes, then ship with fewer preventable issues. They are intentionally lightweight: no setup, no account, and no workflow migration.
Use them as a checklist across your team. Before an ad goes live, build a tagged URL. Before a blog post is published, preview the search snippet. Before a social post is scheduled, check the character count and first-line preview. Before an email sequence is sent, scan the copy for avoidable spam signals.
