Here is the email format its employees use, with an example and a free way to verify an address. By Enrich.chat Editorial. Updated October 15, 2026. **Short answer:** The most common STMicroelectronics email format is first.last@st.com (for example, jane.doe@st.com). Most STMicroelectronics employees follow it. ## What is the email format for STMicroelectronics? STMicroelectronics employees mostly use the first.last format: first.last@st.com, as in jane.doe@st.com for Jane Doe. The pattern below comes from STMicroelectronics addresses we have seen at st.com. Use it to work out a likely address, then verify that address before you send anything. | Format | Pattern | Example for Jane Doe | | --- | --- | --- | | First.last | `first.last@st.com` | `jane.doe@st.com` | **Figure: STMicroelectronics email format, taken apart.** STMicroelectronics employees mostly use [F].[L]@st.com, where the address is split into first name, last name and the company domain. The bars show how often each format appears. *How the format is built (Jane Doe is a made-up name). The bars show the share of addresses at this domain that follow each format.* ## How do I find a specific STMicroelectronics employee's email address? Start from the format, then confirm the exact address. A guessed address that bounces hurts your sender reputation, so check it first. 1. **Apply the format to the person's name.** For Jane Doe at STMicroelectronics, the most likely address is `jane.doe@st.com`. 2. **Verify it.** Enter the name and st.com in the free [email finder](https://enrich.chat/tools/email-finder/) above. It shows whether the address is marked verified, catch-all or unknown in our records. 3. **Start from LinkedIn if you have it.** Paste the person's profile into the [LinkedIn email and phone finder](https://enrich.chat/tools/linkedin-email-finder/) to get the work email and a mobile in one step. 4. **Run a list through your agent.** For many people at STMicroelectronics, paste the prompt below into ChatGPT or Claude. ```text Use www.enrich.chat to find the verified work email for [name] at st.com ``` ## Why might a STMicroelectronics address not follow the format? Most large companies apply one pattern, but not to everyone. Common exceptions: - **Shared names.** A second Jane Doe often gets a middle initial or a number, such as `jane.m.doe@st.com`. - **Acquired teams and subsidiaries.** People who joined through an acquisition can keep the old company's domain for years. - **Contractors and agencies.** They often use their own employer's address, not a STMicroelectronics one. - **Shared inboxes.** Addresses like press@ or careers@ belong to teams, not people. Not sure which pattern applies? The [email permutator](https://enrich.chat/tools/email-permutator/) lists every option for a name, and the [catch-all checker](https://enrich.chat/tools/catch-all-checker/) tells you whether st.com accepts every address, which makes verification less certain. ## Can I email STMicroelectronics employees? You can send relevant business email, but the rules depend on where the person works. In the US, [CAN-SPAM](https://www.law.cornell.edu/uscode/text/15/7704) requires an honest subject line, your postal address and a working opt-out, with no exception for business email. In the UK and EU, a named work address is personal data, so [GDPR and PECR rules for B2B marketing](https://ico.org.uk/for-organisations/direct-marketing-and-privacy-and-electronic-communications/business-to-business-marketing/) apply. Keep messages one to one and relevant. This is not legal advice. ## Frequently asked questions ### What is the STMicroelectronics email format?
