Before a sequence, a subject line, or a follow up plan matters at all, you need the right email address attached to the right person. Here is how to get it without paying for a data provider you do not need yet.
A list of fifty good prospects with guessed email addresses is worse than a list of twenty verified ones. Every bounce chips away at your sender reputation, and a domain with a high bounce rate gets throttled by Gmail and Outlook long before anyone reads your pitch. Verifying the address is the first step, not an optional extra.
Most companies use one email format across the whole team: first.last@, firstinitiallast@, or first@. Find one confirmed address on a team page, press release, or old job listing, then apply the same pattern to the name you actually want to reach.
LinkedIn confirms the name, current title, and company. Combine that with a free pattern lookup tool to guess the format, then verify before sending anything.
Smaller companies often list a direct contact email for press or partnerships on their about page. It rarely belongs to the exact person you want, but it confirms the domain's format instantly.
Several free extensions surface a likely email the moment you open a LinkedIn profile or company site, pulling from public records and pattern matching in the background. Useful for one-off lookups, slower for building a list of more than a handful of contacts.
The fastest option once you are sourcing leads regularly. Instead of checking a name at a time, you search by role, industry, or company size and get a list of already-verified contacts back, ready to drop straight into a sequence. This is the shortcut used in the video above, pulling from lemlist's own database of over 650 million contacts.
If you are going to be prospecting more than a handful of people a week, skip the manual lookups. lemlist's free account includes access to its B2B database, so you can search and export verified emails without piecing together a workflow from three different tools.

A single verification check catches typos, dead domains, and catch-all addresses that will bounce and drag your sender score down. This step takes seconds and saves the reputation of a domain you will need for months.
Finding the address is only the input. Once the list is verified, the next problem is writing something worth opening. That is covered next in our guide to landing your first clients with personalized cold outreach.
