SimpleLogin Alternative: GridInbox vs SimpleLogin for Email Aliases SimpleLogin 替代方案：GridInbox vs SimpleLogin 邮件别名功能对比
Email aliases have become a must-have tool for anyone who wants to control their inbox. Whether you are a privacy advocate trying to keep your real address out of data broker hands, a developer building a multi-tenant SaaS, or a small business owner managing customer support across several departments, the right alias service can save you time and reduce spam. Two names come up often: SimpleLogin, the well known privacy focused tool now part of the Proton family, and GridInbox, a newer multi-tenant platform built for teams and business workflows. This comparison breaks down the differences feature by feature so you can decide which one fits your actual needs.
GridInbox is built as a business grade email alias platform with team features, while SimpleLogin prioritizes individual privacy and encryption.
SimpleLogin started as a privacy tool for individuals. It lets you create unlimited aliases that forward to your real inbox, and you can reply from those aliases. It supports custom domains and integrates with Proton Mail. GridInbox takes a different approach. It is designed from the ground up as a multi-tenant platform for teams and organizations. You get bidirectional aliases (send and receive from any alias), role based access control, shared team inboxes, and a REST API that lets you manage aliases programmatically. If you need to give five support agents access to the same alias inbox while keeping your personal email separate, GridInbox does that out of the box. SimpleLogin does not offer shared inboxes or team roles.
SimpleLogin is ideal for privacy focused individuals, but GridInbox offers stronger business features like team shared inboxes and RBAC.
Privacy and encryption
SimpleLogin uses PGP encryption for forwarded emails and stores data with zero access encryption when used with Proton. GridInbox does not encrypt emails at rest by default. Instead, it relies on the security of the underlying email provider (AWS SES or Cloudflare Email Routing) and supports TLS in transit. For a privacy user who needs end to end encryption, SimpleLogin is the better choice. For a business that needs audit logs, access controls, and shared workflows, GridInbox is more practical.
Team shared inboxes
GridInbox lets you create a shared inbox for an alias like [email protected] and assign multiple team members with different roles (admin, agent, viewer). Each person can send and receive from that alias, and all messages stay in a shared thread. SimpleLogin does not have shared inboxes. If you forward an alias to multiple people, each receives a separate copy and replies are not synced. For a team of three handling customer email, that quickly becomes chaotic.
RBAC: Role based access control in GridInbox means you can restrict who can create aliases, who can delete them, and who can view message history. SimpleLogin has no role system; every user has full control over their own aliases.
Both services support custom domains, but GridInbox allows you to use multiple domains and manage them per team.
SimpleLogin lets you add a custom domain and create aliases like [email protected]. That works well for a personal domain. GridInbox goes further. You can add multiple custom domains, assign different domains to different teams, and set domain wide rules. For example, you can have [email protected] for the support team and [email protected] for marketing, each with its own set of authorized senders and forwarding rules. GridInbox also works with AWS SES and Cloudflare Email Routing, giving you flexibility in email infrastructure. SimpleLogin uses its own forwarding servers.
Custom domain: A custom domain is a domain you own (like yourcompany.com) that you use for email aliases instead of a generic alias service domain.
GridInbox supports full bidirectional send from alias functionality with reply capabilities, while SimpleLogin has limitations on sending.
Both services let you send emails from an alias. SimpleLogin allows reply from alias using a reverse alias system. You get a special reverse alias address in the reply to field, and SimpleLogin rewrites it so the recipient sees your alias. This works but adds a layer of abstraction. GridInbox lets you send directly from the alias using SMTP or the API. You configure the alias with your own SMTP credentials (or use the built in SES integration), and emails go out with the alias as the from address. No reverse alias, no rewriting. For developers building a SaaS that sends emails on behalf of users, GridInbox's direct send is simpler to integrate. For a privacy user who only occasionally replies to forwarded emails, SimpleLogin's reverse alias is fine.
GridInbox provides a full REST API for alias management and email sending, where SimpleLogin's API is more limited.
API capabilities
GridInbox exposes a REST API that covers alias creation, deletion, updating, listing, as well as sending emails, fetching messages, and managing team members. You can automate alias provisioning for new users in your app, or programmatically rotate aliases for security. SimpleLogin also has an API, but it is primarily focused on alias creation and forwarding management. It does not include endpoints for shared inboxes, team roles, or direct email sending. If you are a developer who needs to integrate email alias management into your own product, GridInbox's API is more comprehensive.
Pricing comparison
SimpleLogin offers a free tier with 10 aliases and 1 mailbox. Premium is $3.99/month for unlimited aliases and custom domains. GridInbox starts at $9/month for 50 aliases and 2 team members, with a free tier limited to 10 aliases and 1 user. For an individual who just needs a few aliases, SimpleLogin is cheaper. For a small business with 3 team members and 100 aliases, GridInbox's team plan at $29/month includes unlimited aliases, shared inboxes, and API access. At scale, GridInbox becomes more cost effective because you are paying for team features rather than per alias.
GridInbox works with AWS SES and Cloudflare Email Routing, giving you control over email infrastructure, while SimpleLogin uses its own servers.
If you already use AWS SES for transactional emails, you can route your aliases through the same infrastructure with GridInbox. Cloudflare Email Routing is a free option that handles forwarding and DKIM signing. GridInbox integrates with both, so you can choose your own email provider. SimpleLogin handles all email routing on its own servers. That is simpler but gives you less control. For a business that needs to comply with specific data residency rules or wants to keep email handling inside their own AWS account, GridInbox is the better fit.
GridInbox is a strong SimpleLogin alternative for teams and businesses that need shared inboxes, RBAC, and API driven alias management.
SimpleLogin remains a great choice for individuals who want privacy, encryption, and a simple way to manage personal email aliases. Its Proton integration and zero access encryption are unmatched for privacy. But if you are running a business, managing a team, or building a product that needs programmatic alias control, GridInbox offers features SimpleLogin cannot match: team shared inboxes, role based access, multiple custom domains, direct send from alias, and a full REST API. Evaluate your primary use case. If it is privacy first, go with SimpleLogin. If it is business first, GridInbox is the more capable platform.

邮件别名已成为控制收件箱的必备工具。无论你是希望将真实邮箱地址从数据掮客手中保护起来的隐私倡导者，还是正在构建多租户 SaaS 的开发者，或是需要跨多个部门管理客户支持的小企业主，合适的别名服务都能帮你节省时间并减少垃圾邮件。两个名字经常被提及：SimpleLogin（现已加入 Proton 家族的知名隐私工具）和 GridInbox（一个专为团队和商业工作流打造的新型多租户平台）。本文将从功能层面逐一对比两者的差异，帮助你根据实际需求做出选择。
GridInbox 定位为具备团队功能的企业级邮件别名平台，而 SimpleLogin 则优先考虑个人隐私和加密。
SimpleLogin 最初是为个人打造的隐私工具。它允许你创建无限数量的别名，这些别名会将邮件转发到你的真实收件箱，并且你可以通过这些别名回复邮件。它支持自定义域名并与 Proton Mail 集成。GridInbox 则采取了不同的方法。它从底层设计就是一个面向团队和组织的多租户平台。你拥有双向别名（可从任何别名发送和接收邮件）、基于角色的访问控制、共享团队收件箱以及一个允许你以编程方式管理别名的 REST API。如果你需要让五名客服人员访问同一个别名收件箱，同时保持个人邮箱的独立，GridInbox 开箱即用。SimpleLogin 不提供共享收件箱或团队角色功能。
SimpleLogin 非常适合注重隐私的个人用户，但 GridInbox 在团队共享收件箱和 RBAC 等企业功能上更胜一筹。
隐私与加密
SimpleLogin 对转发的邮件使用 PGP 加密，并与 Proton 配合使用时提供零访问加密存储数据。GridInbox 默认不对静态邮件进行加密，而是依赖底层邮件提供商（AWS SES 或 Cloudflare Email Routing）的安全性，并支持传输中的 TLS 加密。对于需要端到端加密的隐私用户来说，SimpleLogin 是更好的选择。而对于需要审计日志、访问控制和共享工作流的企业来说，GridInbox 更实用。
团队共享收件箱
GridInbox 允许你为 [email protected] 这样的别名创建一个共享收件箱，并分配多个团队成员，赋予不同的角色（管理员、客服、查看者）。每个人都可以通过该别名发送和接收邮件，所有消息都保留在共享的会话中。SimpleLogin 没有共享收件箱。如果你将别名转发给多人，每个人都会收到一份单独的副本，回复也不会同步。对于三个人处理客户邮件的小团队来说，这很快就会变得混乱不堪。
RBAC：GridInbox 中的基于角色的访问控制意味着你可以限制谁能创建别名、谁能删除别名以及谁能查看消息历史。SimpleLogin 没有角色系统；每个用户对自己的别名拥有完全控制权。
两项服务都支持自定义域名，但 GridInbox 允许你使用多个域名并按团队进行管理。
SimpleLogin 允许你添加一个自定义域名并创建类似 [email protected] 的别名。这对于个人域名来说效果很好。GridInbox 更进一步。你可以添加多个自定义域名，将不同的域名分配给不同的团队，并设置域名级别的规则。例如，你可以为客服团队设置 [email protected]，为市场团队设置 [email protected]，每个别名都有自己的一套授权发件人和转发规则。GridInbox 还与 AWS SES 和 Cloudflare Email Routing 兼容，让你在邮件基础设施方面拥有灵活性。SimpleLogin 则使用自己的转发服务器。
自定义域名：自定义域名是你拥有的域名（例如 yourcompany.com），用于创建邮件别名，而不是使用通用的别名服务域名。
GridInbox 支持完整的双向发件别名功能，具备回复能力，而 SimpleLogin 在发送方面存在限制。
两项服务都允许你从别名发送邮件。SimpleLogin 使用反向别名系统实现从别名回复。你会在回复字段中看到一个特殊的反向别名地址，SimpleLogin 会重写它，以便收件人看到你的别名。这虽然可行，但增加了一层抽象。GridInbox 允许你通过 SMTP 或 API 直接从别名发送邮件。你使用自己的 SMTP 凭据（或使用内置的 SES 集成）配置别名，邮件发出时发件人地址就是该别名。无需反向别名，无需重写。对于构建代表用户发送邮件的 SaaS 的开发者来说，GridInbox 的直接发送方式更易于集成。对于只是偶尔回复转发邮件的隐私用户来说，SimpleLogin 的反向别名也足够了。
GridInbox 提供完整的 REST API 用于别名管理和邮件发送，而 SimpleLogin 的 API 功能较为有限。
API 能力
GridInbox 提供了一个 REST API，涵盖别名的创建、删除、更新、列出，以及发送邮件、获取消息和管理团队成员。你可以为应用中的新用户自动配置别名，或以编程方式轮换别名以提高安全性。SimpleLogin 也有 API，但主要侧重于别名创建和转发管理。它不包含共享收件箱、团队角色或直接邮件发送的端点。如果你是需要将邮件别名管理集成到自己产品中的开发者，GridInbox 的 API 更为全面。
定价对比
SimpleLogin 提供免费套餐，包含 10 个别名和 1 个邮箱。高级版每月 3.99 美元，提供无限别名和自定义域名。GridInbox 起步价为每月 9 美元，包含 50 个别名和 2 名团队成员，免费套餐限制为 10 个别名和 1 名用户。对于只需要几个别名的个人用户来说，SimpleLogin 更便宜。对于拥有 3 名团队成员和 100 个别名的小型企业来说，GridInbox 的团队计划每月 29 美元，包含无限别名、共享收件箱和 API 访问权限。在规模扩大时，GridInbox 更具成本效益，因为你是在为团队功能付费，而不是按别名数量付费。
GridInbox 可与 AWS SES 和 Cloudflare Email Routing 配合使用，让你掌控邮件基础设施，而 SimpleLogin 使用自己的服务器。
如果你已经使用 AWS SES 处理事务性邮件，你可以通过 GridInbox 将别名路由到相同的基础设施上。Cloudflare Email Routing 是一个免费选项，负责转发和 DKIM 签名。GridInbox 与两者都集成，因此你可以选择自己的邮件提供商。SimpleLogin 在其自己的服务器上处理所有邮件路由。这更简单，但让你失去了控制权。对于需要遵守特定数据驻留规则或希望将邮件处理保留在自己 AWS 账户内的企业来说，GridInbox 是更合适的选择。
对于需要共享收件箱、RBAC 和 API 驱动别名管理的团队和企业来说，GridInbox 是 SimpleLogin 的有力替代方案。
SimpleLogin 仍然是注重隐私、加密以及希望以简单方式管理个人邮件别名的个人用户的绝佳选择。其 Proton 集成和零访问加密在隐私方面无与伦比。但如果你正在经营企业、管理团队或构建需要程序化别名控制的产品，GridInbox 提供了 SimpleLogin 无法比拟的功能：团队共享收件箱、基于角色的访问、多个自定义域名、直接从别名发送邮件以及完整的 REST API。请评估你的主要使用场景。如果是隐私优先，选择 SimpleLogin。如果是业务优先，GridInbox 是功能更强大的平台。
