Newsletters and marketing emails are easy to over-polish into spam-filter territory. SamuelGuard checks the real email and gives you practical ways to reduce risk before sending.
The subject line shapes both human trust and filter suspicion. It should be specific, honest, and calm.
Campaigns with lots of links, short URLs, tracking-heavy content, or image-only layouts can look suspicious even when the sender is legitimate.
Marketing-style email should make it obvious who sent it and how recipients can opt out.
A screenshot or draft is not enough. Send the actual campaign email through your normal email platform to catch authentication, headers, and layout issues.
For important campaigns, yes. Templates, links, subject lines, and sending platforms change often enough that a quick pre-send test is worthwhile.
No. Inbox placement also depends on list quality, engagement, and mailbox-specific behaviour. A low score means the visible message risks are lower.
SamuelGuard gives you a spam risk score, delivery health, authentication checks, blacklist checks, content warnings, and practical fixes you can act on before the next send.
