Mailor — AI Cold Email That Finds Leads & Writes for You

Mailor is an AI sales copilot that turns a one-sentence product description into a working outbound campaign: it infers your ideal customer profile, finds verified B2B contacts, writes a personalized cold email for each one, and sends them — with optional automated follow-up.

What does Mailor do?

Mailor removes the two slowest parts of cold outreach: deciding who to contact, and writing each email. You describe what you sell; Mailor returns a target ICP, a list of matching leads, and a per-prospect email draft.

• ICP inference — target industry, company size, buyer roles and technographic signals, each returned with visible reasoning you can edit.
• Lead discovery — verified business contacts scored against your ICP and de-duplicated by company.
• AI email writing — per-prospect personalization across six tones and 18 languages, with a spam pre-check before sending.
• Outreach and follow-up — send from a verified domain you control; automated sequences stop the moment a prospect replies.
• Tracking — opens, link clicks, replies, bounces and unsubscribes reported per lead.

How does Mailor work?

Five steps take you from a product description to tracked replies.

1. Describe your product. One or two sentences, or paste your product URL.
2. Mailor infers your ICP. Industry, company size, decision-maker roles and technographic signals — editable before you search.
3. Find matching leads. Verified contacts ranked by fit against the ICP.
4. Generate personalized emails. Each email uses the prospect's company and role context rather than merge fields.
5. Send and track. Dispatch from your sending domain; follow-up sequences run on a schedule you control.

Who is Mailor for?

Mailor is built for founders and lean sales teams that need outbound volume without hiring a dedicated SDR. It fits when you know what you sell but not precisely who buys it, and when you want replies rather than impressions.

How much does Mailor cost?

The free plan includes 50 credits per month with no credit card required. Credits are consumed per action rather than per seat:

Action	Credits
ICP inference	1
Each displayed lead	1
AI email generation	1
Email dispatch	2

Paid plans raise the monthly credit allowance. See pricing for current tiers.

Frequently asked questions

What if I don't know who my ideal customer is?

That is what Mailor is built for. Describe your product in plain language and Mailor proposes the industries, company sizes and decision-maker roles most likely to buy. You review and adjust the profile before anything is sent.

Are the emails really personalized?

Yes. Each email references the prospect's public company information — industry, recent activity, role — combined with your value proposition. The body is generated per prospect rather than filled from a template.

Will my emails land in spam?

Deliverability depends on sender reputation more than on wording. Mailor sends through professional SMTP infrastructure instead of a personal mailbox, includes an unsubscribe link in every email, and pre-checks generated copy for common spam triggers. Warming up a new sending domain before high-volume campaigns remains the highest-impact step.

Do I need my own sending domain?

For production outreach, yes. Sending from a domain you control protects deliverability and brand consistency. A shared sending option is available as a fallback for evaluation.
