Ellie AI vs Agentys: Which Email AI in 2026?
· The Agentys Team
Ellie AI vs Agentys (2026): both draft email replies in your voice automatically. Compare pricing, daily reply caps, voice depth, and whole-inbox triage to pick the right fit.
Ellie and Agentys both draft email replies in your voice automatically — the surprise is how much they now overlap. The real split is reply-drafting with a daily cap versus whole-inbox triage with no cap.
Voice Learning: Both Do It, One Goes Deeper
Both tools personalize. Ellie learns your tone, sign-offs, and writing patterns from your sent mail, and lets you sharpen results with a knowledge base — you paste in facts about your company, products, and clients, and on the higher tiers you can connect data sources so the AI gets the details right (Ellie, 2026). On the Casual plan it trains on roughly your last 200 sent emails. For an individual with a fairly consistent style, that is genuinely enough to produce drafts that sound like you most of the time, and the knowledge base is a clever touch most rivals skip.
Where the two diverge is per-contact nuance. Agentys analyzes about 90 days of sent history and builds a voice model that is keyed to the recipient: the clipped two-line reply you fire at a co-founder, the warmer paragraph you send a long-standing client, the careful register you reserve for a regulator. It learns not just one voice but the way your voice shifts by relationship and context. Most users find that by the second week the per-contact model has filled in enough that the majority of drafts go out with only light edits.
Be honest about what this buys you. If your email is mostly one register — a founder firing off similar replies all day — Ellie's single-voice model plus a knowledge base will get most drafts close. But the per-contact depth is where Agentys pulls ahead, and most inboxes span wildly different relationships: a lawyer alternating between opposing counsel and a nervous client, a sales lead juggling a cold prospect and a signed account. The more your tone has to flex, the more the deeper model is worth having — and Agentys is the one that learns it.
Triage Is the Real Gap
This is the line that actually separates the two products, and it is worth being precise about it. Ellie's job starts at the reply. It looks at the threads that need an answer and writes one — which presumes you have already decided which threads matter. Agentys's job starts one step earlier: it reads everything that came in, labels each message by urgency and type, archives or de-prioritizes the newsletters and notifications, and only then drafts the replies. The drafting is the visible part; the sorting is the part that quietly saves your morning.
That ordering matters because the most expensive thing email does to you is not the typing — it is the interruption and the re-prioritizing. Gloria Mark's research at UC Irvine found it takes an average of 23 minutes and 15 seconds to fully refocus after an interruption (Mark, 2023). An inbox of 80 unsorted messages is 80 little decisions, each one a chance to lose the thread of whatever you were doing. A tool that has already sorted them into "reply now," "reply later," and "ignore" removes most of those decisions before you ever sit down.
So the practical question is whether you need the sort. If you already keep a clean inbox and your only friction is composing replies, you will lean on the drafting more than the triage. If you open Gmail to a wall of 200 messages and freeze, triage is the whole point and a faster reply button barely scratches it — and that is exactly where Agentys's included sorting pulls ahead. Be honest with yourself about which inbox is yours — it is the single best predictor of how much of Agentys you will use.
Pricing: The Honest Numbers
Ellie's ladder is built around how many replies a day you need (Ellie, 2026). There is a free tier that drafts a couple of replies per day on a basic model — genuinely free, no card, good for kicking the tires. The Casual plan is $16.99/mo and lifts you to around 25 replies a day on GPT-4 with basic knowledge-base training. Business is $39/mo per seat for up to 100 replies a day with advanced knowledge base and team features, and Professional is $79/mo per seat for unlimited replies, a customized model, and priority support. A 7-day free trial with no card covers the paid tiers.
Agentys keeps it to two plans: $16.99/mo Starter and $29.99/mo Professional (or $24.99/mo billed annually), with a 7-day free trial. There is no per-day reply cap — the agent drafts as many replies as your inbox warrants — and triage is included at both tiers rather than gated behind the top plan. Note one thing plainly: if you subscribe, monthly plans are refundable within 7 days of the first charge and annual plans within 30 days (via support@agentys.io); the 7-day trial is how you test the fit first.
Put the entry prices next to each other and the honest read is that they are close, but they are not the same product at that price. Ellie's $16.99 Casual and Agentys's $16.99 Starter cost the same, yet Ellie caps you at ~25 replies a day while Agentys does not cap replies and adds whole-inbox triage on top. Ellie also has a free tier for a handful of replies a day, which Agentys does not. But for a working inbox — once your volume is high enough that a daily reply cap stings, or once the sorting is worth as much to you as the drafting — Agentys is the one that keeps up, at the same entry price and with no cap.
