aGo Mail Pilot

aGo Mail Pilot routes WordPress emails through the SMTP server of your choice. Pick a preset for one of 8 supported providers and the in-plugin wizard walks you, step by step, through how to obtain a username and password for that exact provider, with direct links to the right page in the provider dashboard.

This is the differentiator from other SMTP plugins: every preset includes an explainer that opens automatically, in the user’s language (English, Spanish, Brazilian Portuguese). End users no longer have to leave WordPress to figure out that Gmail needs an App Password, SendGrid uses the literal username “apikey”, or Amazon SES uses dedicated SMTP credentials and not the AWS account credentials.

Provider presets included

• Gmail (App Password)
• SendGrid (API key)
• Amazon SES (SMTP credentials from SES console)
• Brevo / Sendinblue (SMTP key)
• Resend (API key)
• MailerSend (SMTP user)
• SMTP2GO (SMTP user)
• Acumbamail (SMTP password)
• Custom (manual entry of any SMTP server)

Features

• SMTP host, port, encryption (TLS / SSL / none), username and password.
• From email and From name.
• Step-by-step credentials wizard per provider (English, Spanish, Portuguese).
• Test email button with the exact SMTP response on failure plus a hint.
• Recent email log (last 10 outgoing messages, stored in the WordPress options table; no extra database table).
• DNS health check: on-demand audit of SPF, DKIM and DMARC records for your sending domain. Read-only DNS queries; nothing is modified.
• Encrypted password storage: AES-256-CBC tied to your WordPress AUTH_KEY. Falls back to base64 only when the WordPress secret keys are placeholders.
• Optional override: define AGOMP_PASSWORD as a constant in wp-config.php and the plugin reads the password from the constant, never from the database.
• Failure rate alerts: optional email to the admin when the failure rate across the last N emails exceeds a configurable threshold. Throttled to one alert per 24 hours.
• No third-party API calls on its own. No remote license server. No telemetry. No premium upsell that breaks the WordPress.org guidelines.

External services

This plugin does not call any third-party API on its own. It connects to the SMTP server that you, the site administrator, configure under aGo Tools, Mail Pilot.

When you save credentials and WordPress sends an email (password reset, plugin notification, contact form, etc.), the plugin opens a standard SMTP connection to the host and port you entered, authenticates with your username and password, and delivers the message. The destination of that connection is whatever server you choose (your own mail server, your hosting provider’s mail server, or a third-party transactional email provider such as Gmail, SendGrid, Amazon SES, Brevo, Resend, MailerSend, SMTP2GO, Acumbamail or any other SMTP service).

The optional DNS health check uses PHP’s built-in dns_get_record() to read SPF, DKIM and DMARC TXT records of a domain you specify. This is a standard DNS query that goes to whatever DNS resolver your hosting server is configured with. No data is sent to aGo Lab or to any third party.

Each SMTP provider has its own terms and privacy policy. Please review them before sending production traffic:

• Gmail: https://policies.google.com/privacy and https://policies.google.com/terms
• SendGrid (Twilio): https://www.twilio.com/legal/privacy and https://www.twilio.com/legal/tos
• Amazon SES: https://aws.amazon.com/privacy/ and https://aws.amazon.com/service-terms/
• Brevo: https://www.brevo.com/legal/privacypolicy/ and https://www.brevo.com/legal/termsofuse/
• Resend: https://resend.com/legal/privacy-policy and https://resend.com/legal/terms-of-service
• MailerSend: https://www.mailersend.com/legal/privacy-policy and https://www.mailersend.com/legal/terms-of-use
• SMTP2GO: https://www.smtp2go.com/privacy and https://www.smtp2go.com/terms
• Acumbamail: https://acumbamail.com/politica-de-privacidad/ and https://acumbamail.com/terminos-de-uso/

No data leaves your site without an explicit administrator action (saving SMTP credentials, running a DNS check) and a WordPress event triggering an email. The plugin does not contact any aGo Lab server at any point.

Privacy

aGo Mail Pilot does not call any third-party API on its own. It does not collect telemetry, usage statistics or personal data. The only outbound network traffic is the SMTP connection that you, the administrator, explicitly configure under aGo Tools, Mail Pilot.

The plugin stores the following on your site:

• SMTP settings (host, port, encryption, username and AES-256-CBC encrypted password) in the wp_options table under the key agomp_settings.
• Email delivery log entries (recipient, subject, status, error message, timestamp) in the wp_options table under the key agomp_log, capped at the last 10 entries. No custom database tables are created.

Deactivating the plugin does not delete the stored data. Uninstalling the plugin deletes both agomp_settings and agomp_log and unschedules the hourly alert cron event.
