Yirlo FAQ: answers before you start

It runs cold email outreach for you. It studies your site, proposes audiences, finds decision makers, verifies their addresses, writes each first email, sends it, and handles the replies. You review the campaigns and the inbox in the app.

Yirlo writes a personal first email for each person, based on their company. Every campaign, audience and email stays editable, and the My copy setting lets you supply your own email copy.

One person. Each company gets a single email from Yirlo, addressed to one decision maker. Writing to several contacts at the same company is coming soon.

Any country or state. Emails go out in the lead's own language where that is supported, or you can pick one of 30 languages for a campaign.

Campaigns run over email at the moment. Coming soon: LinkedIn and other social messaging, along with calling and texting.

Each incoming reply gets a label first, with categories like interested or out of office. Yirlo then drafts a response pointed at the goal you set, such as a call booked through your calendar link, and the draft can go out automatically. Interested replies are also forwarded to you by email as hot leads.

Your results land in your email 3 times a week. Inside the app you can open the full inbox and read any conversation from start to finish.

Results follow your offer and your audience. What Yirlo adds is a daily budget that shifts toward campaigns that earn replies, while weak ones are paused and replaced.

Yirlo handles it for you. It sets up and manages the sending domains and mailboxes, so nothing needs configuring or running on your side.

Yes. Every address is checked before Yirlo sends to it, so you are not paying to email addresses that fail the check.

Coming soon: sending through domains and mailboxes you own. Until that arrives, Yirlo runs the whole sending side itself, using pre-warmed infrastructure that it sets up and maintains for you.

Replies that ask to unsubscribe are labeled as such. You can also keep suppression lists of people and companies through the API, and they apply to every project in your account.

A sent email costs about five cents, deducted from credit you buy in advance. So 1,000 emails cost around $50. There is no subscription, and you pay only for what goes out. Optionally, Yirlo can recharge your account from the card on file as your credit dwindles.

The price covers the whole job: Yirlo researches the companies, identifies the decision makers, and drafts every message. Your bill depends on one thing only, the number of emails that actually go out.

You set a daily budget. Through the API you can also read and set a monthly cap per project and a daily budget per campaign, and check spend by day.

Auto top-up is an optional setting. Switch it on and Yirlo refills your credit by charging your saved card whenever funds get low. Leave it off and you add credit manually.

A lead entry holds the person's name, work email, role, company and company website, along with the campaign that found them. In the app you also see how the conversation is going, and you can mark the deal stage and add a note.

Yes, the app can export all of it as a CSV file. The fields in that file are note, deal_status, conversation, status, audience, website, company, title, last_name, first_name and email.

Every contact is drawn from a pool of over 80M decision makers, and each audience is filled by filtering on job title, seniority, sector, headcount and region. Bringing in a list of your own isn't supported at the moment, though more is planned.

Yes. Use Zapier, n8n or Make with Yirlo's webhooks, or call the API directly, to pass replies and hot leads into Salesforce, HubSpot, Pipedrive or another CRM. You can also export your leads to a CSV file.

Open Settings > Integrations and register as many as 20 HTTPS endpoints. Yirlo posts a JSON payload to them when a genuine reply arrives (reply.received; out of office, unsubscribe and plain no replies are excluded) and when a hot lead is flagged (hot_lead.received). Every request carries an X-Yirlo-Signature header, computed by running HMAC-SHA256 over the body with the endpoint's whsec_ secret. Your endpoint has 5 seconds to answer. Inside the app, each endpoint shows the status of its most recent delivery.

Yes. Zapier, n8n and Make all work through their own generic webhook receivers, since none of them offers a dedicated Yirlo app yet. Use the Webhooks app with a Catch Hook event in Zapier, the Webhook node in n8n, or the Custom webhook module in Make. Then paste the address that tool generates into Yirlo.

An API is available, and every call authenticates with an X-API-Key header. It covers projects, campaigns, inbox conversations, hot leads, webhooks, suppression lists, analytics, and credit and billing. If you already have a list of prospects, you can load it by calling POST /agentapp/campaigns/import, which is live today. A customer's first project is created on yirlo.com, and later projects can be created through the API. Documentation lives at yirlo.com/api-docs.

To start your first project, paste your website address into yirlo.com, and Yirlo comes back with suggested campaigns built around what you sell. Extra projects can also be created from code, using the API, the SDK or the MCP server.

Add teammates from Integrations > Team by entering their email addresses. Everyone logs in with their own address and shares the same project. A CSV download or a webhook into the tools your team already uses also puts results in front of the wider team.

Yes. Campaigns can be edited, stopped and archived, and their daily budgets changed, either in the app or through the API.
