## SenderStack

SenderStack is an AI writing and email productivity platform available as a Chrome extension and a web workspace. It drafts and replies to email in your own voice, lets you chat with multiple AI models, translate and summarize documents, and build simple automations that remove repetitive busywork from your day.

**Preços e planos:** SenderStack uses a freemium model with three paid tiers plus a lifetime option. Free is $0 and includes 5 AI email replies per day, AI composition, AI summaries, and multi-model chat. Starter is $5 per month (about $40 per year when billed annually) with 15 replies per day and 3 AI personalities. Pro is $10 per month (about $80 per year annually) with 75 replies per day, 5 personalities and dedicated support. A Lifetime plan is offered at $199 one-time with 125 replies per day and 10 personalities. No card is required to start and plans can be cancelled anytime; verify current pricing on senderstack.com.

- **AI email reply and compose:** Generate replies, draft new messages, and produce multiple phrasing options from a Gmail sidebar without breaking your workflow.
- **Multi-model AI chat:** Talk to several well-known AI models in one interface and pick the one that fits each research, writing, or summarization task.
- **Chat with PDFs and web pages:** Upload documents or point the assistant at a page to extract answers, summaries, and key points instead of reading everything yourself.
- **Trainable AI personalities:** Create custom personas for professional, casual, sales, or support writing and train them on your own tone so output matches your voice.
- **Automations and campaigns:** Set up recurring responses, scheduled follow-ups, and AI-assisted campaigns to cut repetitive sending work.

**Pontos fortes:** Genuinely usable free tier with 5 AI replies per day; Clear, low-cost paid plans including a $199 one-time lifetime option; Supports multiple AI models instead of locking you to one provider; SOC 2 and GDPR claims plus Google verification and a clean store record

**Limitações:** Email integration is currently limited to Gmail; The free and Starter reply quotas are low for heavy senders; Inbox prioritization is still listed as a feature in development

## Shortwave

Shortwave is an AI-powered email client that layers agentic automation on top of a modern inbox. It organizes, writes, searches, schedules and summarizes email with plain-language prompts, and adds team collaboration features designed to replace the Gmail-plus-Slack workaround.

**Preços e planos:** 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.

**Pontos fortes:** 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

**Limitações:** 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
