Ghost newsletter setup for B2B: domain, list, segments

On Ghost(Pro), sending and deliverability management are part of the plan, with unlimited email sends. Self-hosted, Ghost’s configuration docs say Mailgun is required for bulk mail, and you’re responsible for that account and its setup. The pricing is laid out in Ghost(Pro) vs self-hosted. For most B2B newsletters, Publisher is the starting point. Starter doesn’t have a custom sending domain, which is the next step.

A newsletter from your company domain is more credible to recipients, and to mail filters. Ghost says a custom sending domain is how you tell mailbox providers you’re a real business, while adding that success depends on how established your domain is for bulk mail and on correct DNS. Consider a subdomain such as news.example.com if you’d rather keep newsletter reputation apart from your staff email. Whichever you choose, you’ll publish these records at your DNS host:

The requirement column comes from Google’s email sender guidelines, checked on 30 October 2026. Those limits are for personal Gmail accounts, and Google counts volume per domain. A company’s mail often goes to Microsoft or a corporate filter, so Google isn’t the only test, but its bar is a good minimum. Google also asks for a spam rate below 0.3%, recommends staying below 0.1%, and for bulk senders requires one-click unsubscribe.

B2B doesn’t mean anything goes. These are the UK rules from the ICO’s business-to-business guidance:

• Companies, LLPs and some government bodies are corporate subscribers. PECR’s email marketing rule doesn’t apply to them, but you must identify yourself and give a valid way to opt out.
• Sole traders and most partnerships are treated as individuals, so email marketing generally needs consent or the soft opt-in.
• If you can’t tell which someone is, the ICO says to treat them as an individual. An email address alone won’t tell you.
• A named contact’s details are still personal data under UK GDPR, whichever rule applies.

Other countries differ, some of them sharply, so check the rules where your list actually is. In practice, a newsletter that people asked for performs better anyway, so treat a bought list as off the table.

Ghost’s member import takes a CSV. Clean it first, and carry the data you’ll want later as labels:

email,name,subscribed_to_emails,labels
sam@example.com,Sam Example,true,"customer, uk, it-director"
lee@example.org,Lee Example,false,"prospect, us"

Use subscribed_to_emails honestly, because false keeps someone on file without sending to them. Don’t send your whole historical list on day one. Ghost suggests removing inactive subscribers periodically, and starting from people who recently engaged protects your domain’s reputation while it is new to sending.

Ghost can send to any segment based on the newsletter, the access level and the labels. For B2B, keep the labels few and useful:

• Relationship: customer, prospect, partner.
• Region, where timing or rules differ.
• Role or sector, only if you’ll actually write differently for them.

Use separate newsletters, on the other hand, for what subscribers choose: Publisher allows three, each with its own subscribers and design. A product-update list and a monthly-insight list are good candidates. Use labels for how you choose to target. If you can’t name the email you’d send to a label next month, drop it.

In the newsletter settings, set the sender name, the sender address and the reply-to. Use a person’s name if the writing has a voice, and make reply-to an inbox somebody reads, since a reply is one of the signals that Ghost itself recommends encouraging. Changing the reply-to sends a confirmation to the new address. Add your company’s legal name and postal address in the footer, and make sure the unsubscribe link is plain to see.

Publisher and above include Zapier, n8n, webhooks and the Admin API, so a new sign-up can create a CRM contact and a CRM update can change a label. Decide which system wins when they disagree. An unsubscribe recorded in Ghost must reach the CRM, or sales may email someone who has opted out. Test that path before launch.

1. Send a test to your own addresses at Gmail, Outlook and your company domain.
2. Check that SPF and DKIM pass, in each message’s original headers.
3. Read it on a phone, and click every link.
4. Send first to your most engaged segment, then widen over the next few issues.
5. Watch Ghost’s email analytics, and Google Postmaster Tools if you have a meaningful Gmail audience.

If Ghost is still a question, start with Ghost vs WordPress. If your subscribers are on WordPress today, the migration guide has the order of work. Our Ghost development service covers the theme, sending setup and integrations, and you can tell us about yours here. We have no published Ghost case study. Most of our work is delivered under NDA, so many projects cannot be named.
