Key takeaways
- A work address belongs to the job; a personal address belongs to the person's private life.
- Personal addresses usually need consent for marketing email in the UK.
- A personal address on a bought list is a warning sign about the list.
- When only a personal address exists, reach the person another way.
Work email vs personal email: why the difference matters
The difference matters because a work address is where people expect business offers and a personal address is where they do not. The same message feels routine in one inbox and intrusive in the other.
There is a practical side too. Work decisions are made, forwarded and discussed from work inboxes, so a work address puts your message where it can be acted on.
Can you send a B2B email to a Gmail address
Only with care, and usually only with consent. A free webmail address is often a sign that you are dealing with an individual subscriber, such as a sole trader or a small partnership, and in the UK those need prior consent or the soft opt-in for marketing email.
The exception is narrow: a small business that publishes a webmail address as its own business contact. Even then, the stricter rules for individuals usually apply, so treat it as an inbound route, not a cold one.
How does GDPR treat a personal email address
GDPR treats work and personal addresses alike as personal data, but the legitimate interest balance tips against you with a personal one. A person can reasonably expect job-related offers at work; they rarely expect them at home.
You also have to say where you got the address. If the honest answer is a list of unknown origin, that is hard to put in a privacy notice and harder to defend if the person asks. This is general guidance, not legal advice; check your own position with a data protection adviser.
When is a personal address acceptable
A personal address is acceptable when the person gave it to you for that purpose. Someone who hands you a card with their own address at an event and asks you to follow up has chosen that inbox.
Keep a note of when and how they gave it, and stop using it for marketing the moment they ask. If they later change jobs, ask which address they want you to use rather than assuming.
What should you do if you only find a personal address
Leave the personal address out of your sends and look for a better route. Most people can be reached at work with a little more effort.
- Search again for a work email at their current company.
- Write to the company's general address and ask for the right contact.
- Connect on LinkedIn with a short, specific note.
- Reach a colleague in a related role and ask for an introduction.

Common questions
Is a personal email address personal data under GDPR?
Yes, and so is a named work address. The difference is in the lawful basis you can rely on and what the person can reasonably expect.
What if a prospect replies from their personal address?
Answer the reply where they sent it. Replying to a message they started is not cold outreach, but ask before adding that address to any marketing.
Should a CRM hold personal addresses at all?
Only when there is a reason, such as the person asking you to use it, and with a note of that reason. Otherwise keep the work address as the primary email.
