DeliveryKit SMTP helps you send WordPress emails using SMTP or supported mail APIs.

Email testing * Email logging * Settings import and export * Retention cleanup *
Summary email reports

For more features, see [DeliveryKit SMTP Pro](https://codemasterhub.com/items/deliverykitsmtp-pro/).

### External services

DeliveryKit SMTP only connects to the mail provider that you configure. No provider
API requests are made until you configure and use a provider connection, complete
an OAuth authorization flow, verify a provider account, send a test email, or send
a WordPress email through that provider.

#### Google (Gmail) API

Used to authorize Gmail sending and deliver mail through the Gmail API. When this
mailer is configured or used, the plugin sends OAuth requests, access and refresh
tokens, sender profile lookups, and the sender, recipient, subject, message body,
and attachment data required to deliver the email.

Graph. When this mailer is configured or used, the plugin sends OAuth requests, 
access and refresh tokens, account profile lookups, and the sender, recipient, subject,
message body, and attachment data required to deliver the email.

#### Zoho Mail

Used to authorize Zoho Mail sending and deliver mail through Zoho APIs. When this

If you configure one of the API mailers below, the plugin sends the sender, recipient,
subject, message body, headers, attachment data, and the authentication credential
required by that provider, such as an API key, access token, SMTP username, or SMTP
password, whenever WordPress sends an email or you run a test email.
