Marsell vs Explee: an outbound email agent or an AI that markets and sells
Explee finds B2B buyers and emails them, paid per email at $0.04. Marsell markets and sells with careful outreach. For outbound alone, Explee does more.
By Ilya Arbabi, 13 November 2026
Explee is an outreach agent. You give it your website; its AI researches your market, sharpens your ideal customer, finds high-intent prospects in a database of more than 400 million people, writes each one a personalised email, follows up and books demos, and you pay as you go at $0.04 per email. Marsell is a different kind of tool: an AI that runs a business's marketing and selling together, where outreach is one part, kept small on purpose (one checked first email per prospect, one approach a month, and a no is final). If outbound email to other businesses is the job, Explee does more of it, for less. If you need the marketing as well, the posts, pictures, videos, pages and communities that bring buyers to you, Marsell is built for that, though it is new.
Everything about Explee below comes from Explee's own pages and its public API documentation, read on 13 November 2026.
What Explee is in 2026
Explee describes itself as "Your 24/7 Outreach Agent" and, on its support page, as "an AI agent that finds B2B customers for a business and emails them". AutoGTM, its earlier name, is now Explee. You start with your website address, and the agent does the rest of the chain:
- Finding buyers. Its agents "research the market, sharpen your ICP, find high-intent prospects". The data runs on Explee's own GPU cluster "covering 400M+ people", and its database plans cover up to 105 million companies and more than 80 million decision makers worldwide, with separate sets for the US and the EU.
- Writing. A personalised email for each prospect.
- Sending. Emails go out from Explee's shared mailboxes, with "pre-warmed domains from day one", or from mailboxes bought for your own domain. Each project has a daily budget, and a monthly cap on what it may spend on email.
- Following up. A follow-up setting decides how many emails each sequence has and how far apart they go.
- Replies and CRM. Leads you mark Hot, Demo or Won are pushed to HubSpot.
- LinkedIn. Its support page lists a LinkedIn seat among the things it bills for.
You choose how much it does on its own. Its API documentation says a campaign's lead list waits for you to approve it; with "Auto-manage campaigns" on, it is approved automatically at the end of the project's review window, and with it off, "only approve sends it".
Pricing. The Outreach Agent is pay as you go, with no subscription: $0.04 per email, sold as $30 for 750 emails on the pricing page. Your card is charged for the emails the agent sent, within the daily budget you set. Mailboxes and domains, a LinkedIn seat, data plans and credit packs are billed separately. The database is sold per thousand: deep research from $5 per 1,000 and emails from $10 per 1,000, with semantic search and custom AI enrichment free. The pricing page offers to "Try for free" on both.
Where Explee is stronger
For outbound on its own, Explee does more than Marsell, and the gap is large:
- Volume. A sequence with follow-ups for every prospect, across as many campaigns as your budget allows. Marsell emails each prospect once, approaches a person once a month, and treats a no as final.
- Data. Its own database of companies and decision makers, sold as files or used by the agent. Marsell finds buyers in Reddit threads, communities, directories, creators, search and AI answers rather than from a contact database.
- Price per email. $0.04, with no subscription. Marsell's plans start at $49 a month, though they cover much more than email.
- Infrastructure. Pre-warmed domains and shared mailboxes from the start, or mailboxes on your own domain.
- LinkedIn and HubSpot. A LinkedIn seat is offered, and good leads go to HubSpot. Marsell never sends LinkedIn messages.
- An API. Campaigns, leads and replies can be run from your own code.
What Explee leaves to other tools
Explee does one job. Its pages don't list:
- Marketing content. Posts, pictures, carousels, short videos or films.
- Publishing. Social networks, Google Business Profile or a blog.
- Pages. Building or hosting the pages your emails send people to.
- Ads. Paid campaigns of any kind.
- Buyers outside business email. Its support page says it finds B2B customers. Shops, local services and creators who sell to the public are not who it is described for.
How Marsell's loop works
Marsell runs marketing and selling as one loop:
- You give it a link to your business (or a line about it, or your own AI sets it up over MCP). It reads your pages, products, public mentions and the way you write, and you correct what it got wrong.
- It plans the month and the week.
- It writes the posts and makes pictures, carousels, short videos (motion graphics drawn in code, or AI video) and films, in any of 42 languages.
- It publishes to Instagram, TikTok, YouTube, X, LinkedIn, Threads, Facebook, Pinterest and Bluesky, plus Telegram and Google Business Profile, from accounts you connect. It learns each kind of post from your first few answers, then posts on its own within daily limits. Every post has a 24-hour undo.
- It looks for buyers in Reddit threads, communities, directories, creators, search and AI answers. Its Outreach agent sends each new prospect one checked first email, written from something true about them, from mailboxes Marsell sets up, once you press Start at a price you pick: one approach a month, and a no is final. Sell drafts the follow-ups and an answer to every reply.
- It builds and hosts pages, counts visits without cookies and reports what worked.

Who should pick which
Pick Explee if
- You sell to other businesses, and outbound email is how you win them.
- You want follow-up sequences and more volume than a careful first email.
- You want to pay per email rather than a monthly plan.
- You want a contact database you can also export.
Pick Marsell if
- Your buyers find you through posts, search, communities and AI answers as much as through email.
- You want outreach kept small: one checked email, one approach a month, and a no is final.
- You want the marketing made and published in the same place as the selling.
- You are fine with a new tool.
You can use both. If you do, let Explee handle cold email to businesses and keep Marsell's outreach off, so nobody hears from you twice.
Where Marsell fits
Marsell is an AI marketer that markets and sells a business on autopilot. It learns each kind of work from your first few answers, then does it on its own within daily limits. Every post has a 24-hour undo, and you can steer or pause it any time. Money is the exception: ad spend moves only when you say so. It is new, and its first customer is Marsell itself.
Plans are Solo $49, Core $169, Growth $399 and Network $799 a month, each with monthly tokens for the model and media work, and every paid action shows its price in tokens first. Ad spend is paid to the ad network separately. There is no free plan or trial, but the first look at your link is free.
