## Shortwave

Shortwave was built by a team of ex-Googlers and is often described as the spiritual successor to Google Inbox. Its starting point is a faster, more organized inbox: tabs and bundles separate what matters from newsletters and promotions, emails convert into a prioritized to-do list, delivery schedules keep interruptions off your clock, and keyboard-first navigation keeps your hands off the mouse. Read receipts and link tracking add the context you normally only get from a sales tool.

The AI layer is where the product has moved furthest. Shortwave's agent works like an assistant inside the mailbox: give it a prompt and it will organize messages, draft replies in your own writing style, check availability and create calendar events, or analyze an entire team's mail and attachments to answer a question. AI filters written in plain English replace traditional rule builders, and autocomplete suggests real links, facts and phrases pulled from your own email history.

Team features address a familiar problem — discussing email in a separate chat app. Shared threads update in real time, teammates can leave private comments on a message, assignments create a clear owner, and shared labels build a common searchable archive. The platform reports CASA Tier 2 compliance, privacy features such as an image proxy and tracking-pixel blocking, and integrations with Slack, Notion, Asana, HubSpot and a sister product, Tasklet, for broader workflow automation. Clients are available for iOS, Android, Mac and Windows.

**Pricing & Plans:** Freemium with a free plan and no credit card required to start. Paid personal and business tiers unlock higher AI usage limits and advanced automation, including the Tasklet workflow product; a free trial is available.

- **Agentic AI assistant:** A conversational agent that organizes your inbox, identifies what matters, drafts replies, writes scheduling emails and runs multi-step workflows from a single prompt.
- **Automatic inbox organization:** Plain-language AI filters and scripts that automatically label, archive, star or sweep messages so you reach inbox zero faster.
- **AI search across email and files:** Ask questions in natural language and search across your own messages — or your whole team's emails and attachments — to get answers rather than links.
- **Real-time team collaboration:** Shared threads, private comments, assigned next steps and shared labels give a team one live view of important conversations.
- **Scheduling and follow-up tools:** Calendar checking, event creation, smart snooze suggestions, delivery schedules, link tracking and follow-up reminders all run inside the inbox.

**Strengths:** Genuinely agentic AI rather than a bolt-on summarize button; Collaboration features remove the need to paste screenshots into Slack; Keyboard-first, fast interface with a modern inbox layout; Broad integration set including Slack, Notion, Asana and HubSpot

**Limitations:** It is a full email client, so migrating means bringing your inbox and workflow with you; Advanced automation lives in paid tiers; Some features depend on connecting external tools like Slack, Notion and HubSpot; The feature set is deep enough that new users need time to learn the automation model

## Spamdrain

Spamdrain is an independent antispam service operated by Spamdrain AB, a company based in Gothenburg, Sweden. Rather than replacing your email provider, it attaches to the accounts you already use and screens incoming messages, so you keep your familiar address while gaining a filtering layer. The team says it has been refining its filtering technology since 2004, which shows in how quickly the system reacts to new spam campaigns.

Setup is intentionally simple: connect an email account, and Spamdrain starts judging new messages. Anything it accepts is passed through to your inbox, anything suspicious is held back, and occasionally you review the quarantine and confirm or override decisions. Those corrections train your personal filter, so results improve the longer you use it.

The service covers the platforms most people actually use, including iPhone, Android, Mac, Windows, Office 365 and general IMAP/POP mailboxes. It blocks spam, phishing links, malicious attachments and automated bulk mail, with a free 14-day trial so you can test it against your own inbox before paying.

**Pricing & Plans:** Free 14-day trial, then a low-cost paid subscription that Spamdrain describes as costing less than a cup of coffee. Exact plan prices are shown after sign-up or on the pricing page.

- **Multi-platform email coverage:** Works with iPhone, Android, Mac, PC, Office 365 and general IMAP/POP accounts, so one filter protects every device that reads the same mailbox.
- **Phishing, virus and spam blocking:** Every new message is analysed before delivery, and suspicious senders, malicious links and infected attachments are stopped instead of reaching you.
- **Adaptive personal filter:** Each time you mark something as spam or confirm it is legitimate, the filter learns your preferences and gets more accurate over time.
- **Reviewable quarantine:** Held messages are not lost. You can open your Spamdrain account, inspect what was blocked, and release false positives with a click.
- **Newsletter control:** Separate the newsletters you want from the bulk mail you never signed up for, so only the senders you care about get through.

**Strengths:** Simple setup: connect an account and filtering begins immediately; Covers iOS, Android, macOS, Windows, Office 365 and standard mail providers; Filter improves with your own corrections, not just global rules; Free 14-day trial lets you test on real mail before subscribing

**Limitations:** Pricing details are not fully published without going through sign-up; Quarantine still requires occasional manual review to avoid losing legitimate mail
