## Ready to Send

: Ready to Send is a Gmail productivity app that takes over the repetitive work of writing replies. Once installed from the Google Workspace Marketplace, it watches your inbox for new and unread messages that expect an answer, deliberately filters out newsletters, promotions, and automated notifications, and generates a complete prewritten response that appears as a draft for your review.

The personalization layer is what makes drafts usable rather than generic. You can set global writing instructions, add special rules for individual contacts, and create Intelligent Snippets — short pieces of reusable content such as refund policies, pricing details, shipping terms, or onboarding steps. When an email touches on those topics, the AI pulls the relevant snippet straight into the draft, so answers stay accurate and consistent across the team or across your own correspondence.

Under the hood, Ready to Send defaults to the newest OpenAI model and supports connecting your own API key for Google Gemini and Anthropic Claude. It handles more than 100 languages, detecting the language of an incoming message and replying appropriately. The app works in native Gmail on Android and iOS as well as third-party clients that surface Gmail drafts. The company states that emails are not stored and that language models are not trained on your messages, and it has passed a Cloud Application Security Assessment Tier 2 audit. A free allowance of AI-generated emails lets you test it before subscribing.

**Pricing & Plans:** Ready to Send offers a free starting allowance advertised as 100 to 200 AI-generated emails, so you can evaluate it before paying. Paid plans are sold as a monthly subscription with frequent promotional discounts on the first month. Exact tiers should be confirmed on the vendor's plans and pricing page, as published amounts change.

- **Automatic draft replies for Gmail:** Ready to Send scans your inbox for new, unread messages that need a response and drafts a contextual reply based on your personalization settings, typically within a few minutes of arrival.
- **Per-contact tone and instruction profiles:** Write reply instructions globally or per contact so the AI matches your tone for different relationships, and set up predefined profiles for specific people or scenarios.
- **Intelligent Snippets knowledge base:** Build a reusable content library of policies, pricing, procedures, and common answers, and the AI inserts the most relevant snippet into the draft automatically.
- **Inbox filtering and manual generation:** Smart filtering skips newsletters, promotions, automated notifications, vacation autoresponders, and no-reply addresses. You can also trigger drafts from Gmail labels or generate one manually.
- **Flexible model choice and 100+ languages:** Run on the latest OpenAI model by default, or connect your own API key for Google Gemini or Anthropic Claude. Replies can be drafted in 100+ languages and drafts sync across Gmail on desktop, Android, and iOS.

**Strengths:** Drafts appear automatically in Gmail without leaving your existing workflow; Intelligent Snippets keep policy and pricing answers consistent across a team; Per-contact instructions let you vary tone by relationship; Works across desktop and mobile Gmail, in 100+ languages

## SenderStack

SenderStack positions itself as a complete AI writing assistant rather than a single email trick. The core loop is simple: connect your Google account, install the Chrome extension, and let the assistant learn your tone. From there you can compose or reply to mail in a sidebar, generate multiple subject-line and body variants, summarize long threads, translate messages, correct grammar, and ask questions about an attached PDF or a web page without leaving your inbox.

The product also ships a multi-model chat, so users are not locked to a single provider and can route different tasks to different language models. On top of that sits a lightweight automation layer: recurring email responses, scheduled follow-ups, and reusable AI personalities tuned for contexts such as professional, casual, sales, or support writing. The team markets the platform around time savings, citing internal productivity claims for email automation and PDF chat.

Pricing is transparent and unusually broad for the category, spanning a genuinely usable free tier, low-cost monthly subscriptions with an annual discount, and a one-time lifetime purchase. The publisher states compliance with SOC 2 controls and GDPR, and the extension is Google-verified with a clean Chrome Web Store record. Note that the current integration focus is Gmail; other inbox providers are described as future work.

**Pricing & Plans:** 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.

**Strengths:** 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

**Limitations:** 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
