Tomba for Thunderbird
Find and verify email addresses directly in your Thunderbird email client. Enrich contacts as you compose emails.
// 01 · in the popup
Every tool, one click from the page
Open a company's website and click Tomba. The popup has the people and their verified addresses, the company, what its site runs and the companies like it, with what each lookup costs before you spend it.
Everyone at the company you are looking at
The addresses Tomba knows at the domain, with each person's role and department, whether the address is verified and where it was found. Filter by department, name, type or country; save the ones you want to a leads list.
Check an address before you write
Format, domain type, mail server, deliverability and MX records, with a verdict and a risk level. Verification uses verification credits, not search credits.
Reach them by phone
The numbers Tomba has for an address, with the line type, the country and the carrier, in local, international and E.164 formats. Charged only when a valid number comes back.
Know the company first
What the company does, where it is, its size and industry, its email pattern and whether its server accepts every address.
// 02 · in your inbox
Who is the sender?
Open a message and Tomba looks up its sender: the person, their role and their company, and the company's other addresses. A webmail or disposable sender is not looked up.
