AppRanks verdict
Generated from live marketplace data — refreshed daily
SMTP URI and logging is a newly-listed WordPress app with a limited review volume. It is listed in the Email category on WordPress Plugin Directory, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. no published reviews yet means feature claims are unverified by the wider merchant base. Without a published review base, the only fit-signal available is the developer's own documentation plus the marketplace's listing-quality audit (linked below). Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.
Pros
- +Published by Viktor Szépe — established developer track record

For fully SSL encrypted connection (SMTPS) start it with smtps:// – the default port is 465.
