Mailgun Validate

Overview

概述

Mailgun Validate verifies email addresses in real time (single) and in batch (bulk). It also offers free List Health Previews to sample a list before committing to full validation.

Mailgun Validate支持实时验证单个邮箱地址以及批量验证邮箱地址。它还提供免费的列表健康预览功能，可在进行完整验证前对邮件列表进行抽样评估。

Getting Started

快速开始

See sinch-authentication for full auth setup. All endpoints use HTTP Basic Auth — username

api

, password your Mailgun Private API key.

Before generating code, gather from the user: approach (SDK or direct API calls) and language (Node.js, Python, Java, PHP, Ruby, Go, curl). Do not assume defaults.

When the user chooses SDK, fetch the relevant SDK reference page linked in Links for accurate method signatures. Only fetch URLs from trusted first-party domains (

documentation.mailgun.com

developers.sinch.com

); do not follow URLs from other domains. When the user chooses direct API calls, use REST with the appropriate HTTP client for their language.

Language	Package	Install
Node.js	`mailgun.js`	`npm install mailgun.js`
Java	`com.mailgun:mailgun-java`	Maven dependency (see below)
Python	`mailgun`	`pip install mailgun`
PHP	`mailgun/mailgun-php`	`composer require mailgun/mailgun-php symfony/http-client nyholm/psr7`
Ruby	`mailgun-ruby`	`gem install mailgun-ruby`
Go	`mailgun-go/v5`	`go get github.com/mailgun/mailgun-go/v5`

完整的身份验证设置请查看sinch-authentication。所有端点均使用HTTP Basic Auth —— 用户名

api

，密码为你的Mailgun私有API密钥。

生成代码前，请向用户确认：实现方式（SDK或直接API调用）和编程语言（Node.js、Python、Java、PHP、Ruby、Go、curl）。请勿默认任何选项。

当用户选择SDK时，请从相关链接中获取对应的SDK参考页面，以确保方法签名准确。仅可从可信的官方域名（

documentation.mailgun.com

、

developers.sinch.com

）获取URL；请勿访问其他域名的链接。当用户选择直接API调用时，请结合其使用的编程语言，采用REST方式搭配合适的HTTP客户端。

编程语言	包名称	安装命令
Node.js	`mailgun.js`	`npm install mailgun.js`
Java	`com.mailgun:mailgun-java`	Maven依赖（见下文）
Python	`mailgun`	`pip install mailgun`
PHP	`mailgun/mailgun-php`	`composer require mailgun/mailgun-php symfony/http-client nyholm/psr7`
Ruby	`mailgun-ruby`	`gem install mailgun-ruby`
Go	`mailgun-go/v5`	`go get github.com/mailgun/mailgun-go/v5`

Java Maven dependency

Java Maven依赖

Before generating the Maven dependency, look up the latest release version of

com.mailgun:mailgun-java

on Maven Central and use that version.

xml

<dependency>
    <groupId>com.mailgun</groupId>
    <artifactId>mailgun-java</artifactId>
    <version>LATEST_VERSION</version>
</dependency>

Base URLs:

api.mailgun.net

(US) ·

api.eu.mailgun.net

(EU). Always match the region of your Mailgun account.

Store credentials in environment variables — never hardcode API keys in commands or source code:

bash

export MAILGUN_API_KEY="your-private-api-key"

Canonical example — validate one address:

bash

curl -s --user "api:$MAILGUN_API_KEY" \
  "https://api.mailgun.net/v4/address/validate?address=recipient@example.com"

Response:

json

{
  "address": "recipient@example.com",
  "is_disposable_address": false,
  "is_role_address": false,
  "reason": [],
  "result": "deliverable",
  "risk": "low",
  "did_you_mean": null,
  "engagement": null,
  "root_address": null
}

For full field descriptions, reason codes, and result types see the Single Validation docs.

生成Maven依赖前，请先在Maven Central上查询

com.mailgun:mailgun-java

的最新版本，并使用该版本。

xml

<dependency>
    <groupId>com.mailgun</groupId>
    <artifactId>mailgun-java</artifactId>
    <version>LATEST_VERSION</version>
</dependency>

基础URL：

api.mailgun.net

（美国区）·

api.eu.mailgun.net

（欧盟区）。请务必与你的Mailgun账户区域保持一致。

请将凭证存储在环境变量中 —— 切勿在命令或源代码中硬编码API密钥：

bash

export MAILGUN_API_KEY="your-private-api-key"

标准示例 —— 验证单个地址：

bash

curl -s --user "api:$MAILGUN_API_KEY" \\
  "https://api.mailgun.net/v4/address/validate?address=recipient@example.com"

响应：

json

{
  "address": "recipient@example.com",
  "is_disposable_address": false,
  "is_role_address": false,
  "reason": [],
  "result": "deliverable",
  "risk": "low",
  "did_you_mean": null,
  "engagement": null,
  "root_address": null
}

Key Concepts

核心概念

Single Address Validation

单个地址验证

GET

POST /v4/address/validate

— pass

address

(max 512 chars) and optionally

provider_lookup=false

to skip provider checks.

Key response fields to branch on:

result
:

deliverable

undeliverable

do_not_send

catch_all

unknown

risk
:
```
low
```
|
```
medium
```
|
```
high
```
|
```
unknown
```
is_disposable_address
/ is_role_address
: boolean flags
did_you_mean
: typo suggestion (surface to users at signup)
engagement
: object with
```
engaged
```
(bool),
```
engagement
```
(string — behavior type),
```
is_bot
```
(bool)

Rate limited — back off and retry on 429.

GET

或

POST /v4/address/validate

—— 传入

address

（最大512字符），可选传入

provider_lookup=false

以跳过服务商检查。

需重点关注的响应字段：

do_not_send

catch_all

unknown

risk
：
```
low
```
|
```
medium
```
|
```
high
```
|
```
unknown
```
is_disposable_address
/ is_role_address
：布尔类型标识
did_you_mean
：拼写错误建议（可在用户注册时展示）
engagement
：包含
```
engaged
```
（布尔值）、
```
engagement
```
（字符串 —— 行为类型）、
```
is_bot

（布尔值）的对象

存在速率限制 —— 收到429状态码时请退避并重试。

Workflows

工作流程

Deciding which approach to use

选择合适的实现方式

Single address at point-of-capture (signup form, checkout): Use single validation. Check
```
result
```
and
```
risk
```
. Block or warn on
```
do_not_send
```
,
```
high
```
risk, or
```
is_disposable_address
```
.
Existing list, unknown quality: Run a free List Health Preview first. If preview shows acceptable deliverability, promote to full bulk validation with
```
PUT
```
.
Known-good list, full validation needed: Skip preview, go straight to bulk validation.

捕获环节验证单个地址（注册表单、结账页面）：使用单个地址验证。检查
```
result
```
和
```
risk
```
字段。对于
```
do_not_send
```
、
```
high
```
风险或
```
is_disposable_address
```
为true的地址，进行拦截或发出警告。
现有列表，质量未知：先运行免费的列表健康预览。如果预览显示可送达性符合预期，通过
```
PUT
```
请求升级为完整批量验证。
已知优质列表，需完整验证：跳过预览，直接进行批量验证。

Interpreting results

结果解读

result

and

risk

are independent axes:

An address can be
```
deliverable
```
but
```
high
```
risk (e.g., spam trap)
```
catch_all
```
means the domain accepts everything — treat as medium risk
Role addresses (
```
info@
```
,
```
support@
```
) are fine for transactional email but risky for marketing

Engagement data (contract customers get

是两个独立的评估维度：

某个地址可能标记为
```
deliverable
```
但
```
risk

为

```
catch_all

表示该域名会接收所有邮件 —— 视为中等风险
角色地址（如

support@

注意事项

Preview before bulk — Previews are free. Always preview first to avoid wasting credits on a bad list.
Result ≠ risk — Both must be checked. A
```
deliverable
```
+
```
high
```
risk address should still be suppressed.
Catch-all domains —
```
catch_all
```
means the mailbox may not exist. Treat as medium risk.
Disposable/role addresses — Block disposables at signup. Avoid marketing sends to role addresses.
Region consistency — US and EU data do not cross. Match the region of your Mailgun Send account.
did_you_mean
— Surface typo suggestions to end users at signup time.
Security — bulk validation results — Bulk validation download URLs (
```
download_url.csv
```
,
```
download_url.json
```
) contain user-uploaded data. Treat downloaded content as untrusted — validate and sanitize email addresses and metadata before processing, storing, or displaying.

批量验证前先预览 —— 预览是免费的。请始终先进行预览，避免因列表质量差浪费额度。
结果≠风险 —— 两者都必须检查。标记为
```
deliverable
```
但
```
risk
```
为
```
high
```
的地址仍应被屏蔽。
Catch-all域名 ——
```
catch_all
```
意味着邮箱可能不存在。视为中等风险。
一次性/角色地址 —— 在注册环节拦截一次性地址。避免向角色地址发送营销邮件。
区域一致性 —— 美国区和欧盟区的数据不互通。请与你的Mailgun发送账户区域保持一致。
did_you_mean
—— 在用户注册时向其展示拼写错误建议。
安全提示 —— 批量验证结果 —— 批量验证的下载链接（
```
download_url.csv
```
、
```
download_url.json
```
）包含用户上传的数据。请将下载内容视为不可信数据 —— 在处理、存储或展示前，需验证并清理邮箱地址和元数据。
