Holographic SMTP Helper helps WordPress send email through a proper SMTP mailbox or SMTP relay. It is built for site owners who want a clean setup screen, clear test results and useful logs without bloat.
Start with the Setup Wizard. You can enter the email address your website will send from, let HoloSMTP look for public SMTP settings, or choose a known provider from the list. Then enter your SMTP username and password or key, save the settings and send one test email.
If a test fails, HoloSMTP saves the error and explains the likely problem in plain English. It can point out common issues such as the wrong host, the wrong port, the wrong encryption setting, a missing app password, SMTP AUTH being disabled, a From email address the provider will not allow, or missing SPF, DKIM and DMARC records.
The plugin includes email logs so you can see what WordPress tried to send, who it was sent to, whether it was accepted, and what error was returned if it failed. Message body logging is off by default because email content can contain personal or sensitive information.
Saved SMTP passwords are never shown back on the settings screen and are not included in exported settings. The plugin does not add front-end scripts, tracking, licence checks, paid feature gates or upgrade prompts.
Automatic setup checks are only run by an authorised administrator from the Setup Wizard. Discovery may contact public setup URLs and DNS records for the email domain you enter. Some provider-standard checks may include that email address. HoloSMTP does not send SMTP passwords, API keys, saved logs or email content during discovery.
