How to Start a Newsletter for Your Agency: Beehiiv Tutorial (2026)

• It gives you an owned follow-up channel. Social reach fluctuates. Your email list does not depend on an algorithm.
• It shortens the gap between interest and purchase. Most prospects do not book a call the first time they find you, but they may read you for weeks.
• It compounds authority. One useful issue per week turns scattered insight into a repeatable trust asset.

1. Pick one promise and one cadence. Name the newsletter around a clear reader outcome, not around your agency name alone. Weekly is enough for most teams. CTA: open Beehiiv only after you can finish this sentence: "Every week, we help [audience] do [specific job] better."
2. Create the publication and connect the brand. Beehiiv's Launch plan includes custom domains, so start the publication on a company subdomain like newsletter.youragency.com instead of a generic hosted URL. CTA: create the publication shell and connect the domain before writing the first issue. Sources: Beehiiv pricing and Beehiiv custom domains.
3. Import the list you already have. Start with past clients, warm prospects, and hand-raisers who should reasonably expect to hear from you. Do not buy a list. CTA: import the warm contacts now, even if the first list is small. Source: Importing subscribers into Beehiiv.
4. Set the welcome path. If you are on Launch, send the first few messages manually. If you move to Scale, Beehiiv adds email automations. CTA: write the welcome email before you design anything else, because new subscribers need to know what they signed up for immediately. Source: Beehiiv pricing.
5. Publish issue one and measure response, not polish. Beehiiv gives Launch users basic publication analytics and paid plans deeper website analytics. CTA: publish the first issue this week, then review clicks, replies, and subscriber growth before you touch templates again. Sources: Beehiiv pricing and Beehiiv website analytics.

The pattern is simple: set expectations, prove usefulness, then earn the commercial ask. Most agencies invert that order and wonder why the newsletter feels promotional from day one.

• Net subscriber growth: are more qualified readers joining than leaving?
• Click-throughs to your site or offer: this matters more than vanity open-rate interpretation.
• Replies: for service businesses, direct replies are often the clearest signal that the right people are paying attention.
• Booked calls or attributed leads: measure whether the newsletter actually supports pipeline, not just audience size.
