ReadyGo SMTP

ReadyGo SMTP fixes WordPress email delivery by routing your mail through trusted providers instead of the unreliable default mail() function — and it goes further with weighted load-balancing and automatic failover so a single provider outage never stops your email.

Connect one or more providers, decide how mail is routed between them, and watch every send in a clean dashboard with logs and charts.

Key features

• Multiple providers — Any SMTP server plus native API integrations for Amazon SES, SendGrid, Mailgun, Postmark, Brevo (Sendinblue), SparkPost, SMTP2GO, Elastic Email, Netcore, Gmail / Google Workspace, Microsoft Outlook, ToSend, and PHP mail().
• Weighted load-balancing — split sending across connections by weight (e.g. 70/30).
• Automatic failover — if one connection fails, the next is tried instantly; a failing connection is briefly cooled down, then retried.
• Email logging — every message recorded with status, recipient, subject and the full failover trail. Resend with one click.
• Dashboard and reports — sending volume over time, success rate, and a send-time heatmap.
• Forced From identity — set and enforce the From name/email and Return-Path for better deliverability.
• Test email tool — send a test (HTML or plain) through your real routing.
• Log retention — auto-purge old logs on a schedule you choose.

Why use it

WordPress’s built-in mail often lands in spam or fails silently. Routing through a real SMTP/API provider with proper From identity and authentication dramatically improves inbox placement — and load-balancing plus failover keep your transactional and form emails flowing even when a provider has problems.

External services

ReadyGo SMTP does not contact any external service on its own. It only sends your outgoing WordPress email through the third-party mail provider(s) you choose and configure with your own credentials. Nothing is sent anywhere until you add and enable a connection, and no usage data, analytics, or telemetry is ever collected by the plugin.

When you enable a provider, your outgoing message data — the recipient address(es), subject, body, and headers — is transmitted to that provider each time WordPress sends an email (for example a contact-form notification, a password reset, or a WooCommerce order email), so the provider can deliver it on your behalf. Data is only sent to the specific provider(s) you connect; deactivating a connection stops any further data being sent to it.

Each provider is an independent company operating under its own terms of service and privacy policy. Review the one(s) you enable:

Standard SMTP connections (the «Other SMTP» option) send your mail to whatever SMTP host you configure; no third-party service is involved beyond the server you specify.
