Send WordPress email through SMTP.com
Connect WordPress to SMTP.com through NimblyMail SMTP for established, enterprise-grade transactional email delivery.
Why pair SMTP.com with NimblyMail
SMTP.com is a long-established transactional email provider (over two decades in the space) known for deliverability guarantees and dedicated support, making it a solid choice for WooCommerce stores that want an enterprise-grade sending partner without a large agency contract. NimblyMail SMTP connects your WordPress site using SMTP.com’s API key, routing order notifications and system email through its infrastructure.
SMTP.com has been sending transactional mail since before “email deliverability” was a mainstream concern, and it leans on that track record with deliverability guarantees and hands-on support that smaller providers typically don’t offer. For stores that have been burned by mail landing in spam with a budget provider, SMTP.com’s more established infrastructure and account support are the selling point.
SMTP.com’s modern integration path is API-key based rather than a traditional SMTP username/password pair, which simplifies credential management — one key controls access, and it can be revoked or rotated from the dashboard without changing any other account settings.
Connect SMTP.com in three steps
Generate an API key
In your SMTP.com dashboard, go to your account's API settings and generate an API key, and note your verified sender name/address under the Senders section.
Configure NimblyMail
In WordPress, go to NimblyMail SMTP > Settings, select SMTP.com, and enter the API key and sender name from step 1. SMTP.com's primary modern integration path is API-key based rather than a documented public SMTP relay hostname/port — verify against SMTP.com's current dashboard/documentation whether a traditional SMTP relay option is also available for your account before assuming host/port values.
Send a test email
Send a test email from NimblyMail to confirm authentication and delivery.
Add and verify SPF and DKIM records for your sending domain from your SMTP.com dashboard's domain/sender verification section to your DNS zone — this is required for reliable inbox delivery and to unlock full sending reputation.
SMTP.com + WordPress, answered
SMTP.com's current WordPress-facing integrations are built around its API key, not a documented public SMTP hostname — treat this as an API-based connection unless your account dashboard shows otherwise.
SMTP.com is generally positioned as a paid, enterprise-oriented service; check current plans in your dashboard, as free/trial availability changes.
Its long operating history, deliverability guarantees, and direct support are the main differentiators — it's aimed at businesses that want a sending partner, not just a relay.
Dedicated IP options are typically available on higher-tier SMTP.com plans — check your account's plan details for eligibility.
Confirm the sender address entered in NimblyMail exactly matches a verified sender/domain in your SMTP.com dashboard — mismatches are the most common cause of rejected sends.
