SMTPBloom
Every email delivered, every time
SMTPBloom replaces WordPress's unreliable default mail function with a proper authenticated SMTP connection to SendGrid, Mailgun, Amazon SES, Gmail, Outlook, and 15+ other providers — eliminating spam delivery in five minutes or less. WP Mail SMTP charges $49/year for features like backup SMTP, email logging, and OAuth support that SMTPBloom includes as standard in a one-time purchase. Every email your site sends — order confirmations, password resets, contact forms — reaches the inbox it was meant for.

One-Click Provider Setup
Pre-configured connection wizards for SendGrid, Mailgun, Amazon SES, Postmark, SparkPost, Gmail, Outlook, and 10+ more — enter your API key and you're sending in under two minutes.
Complete Email Logging
Every email sent by WordPress, WooCommerce, or any plugin is logged with full headers, recipient, subject, body preview, send timestamp, and delivery status.
Delivery Analytics Dashboard
Track send volume, delivery rate, bounce rate, and open rate over time in a clean dashboard — identify deliverability problems before they affect your users.
OAuth 2.0 for Gmail & Outlook
Authenticate with Google and Microsoft via OAuth 2.0 without storing app passwords — more secure, more reliable, and unaffected by two-factor authentication changes.
Backup SMTP Failover
Configure a secondary SMTP provider that activates automatically if your primary fails, ensuring zero email downtime even during provider outages.
Custom From Address & Name
Force all WordPress emails to use your professional domain address and a consistent From name, replacing the generic wordpress@yoursite.com that most spam filters flag.
Send Test Email Tool
Send a test email to any address and receive a detailed diagnostic report covering connection success, authentication, send time, and any error codes returned.
Resend Failed Emails
Retry individual failed emails directly from the log with one click, or bulk-resend all failed deliveries from a selected time period.
Email Log Search & Filter
Search the full email log by recipient, subject, status, or date range — essential for diagnosing "I never got the order confirmation" support requests in under 30 seconds.
DKIM, SPF & DMARC Guidance
Built-in DNS record checker verifies your DKIM, SPF, and DMARC records and provides the exact DNS entries needed to pass authentication checks and maximize deliverability.
WooCommerce Email Preview
Preview and test every WooCommerce transactional email (order confirmation, shipping notification, invoice) through your SMTP connection before a real order triggers them.
WP-CLI Email Testing
Run smtp-bloom test from the command line to validate SMTP connectivity and send test emails as part of automated site health checks.
