Email Marketing Campaign: Types and How to Build One
An email marketing campaign is a planned send, or series of sends, aimed at one audience with one goal. A product launch to existing customers is a campaign. So is a five-email nurture sequence for people who downloaded a guide, or a win-back series for contacts who stopped clicking. What makes it a campaign, rather than just “an email,” is that it has a defined audience, a single call to action and a way to tell whether it worked.
Key takeaways
- One campaign, one goal, one call to action. Everything else is a distraction.
- Segment before you write. The same message to everyone usually underperforms.
- Judge campaigns on clicks, replies and conversions, and do the math before you send.
Types of email marketing campaigns
| Campaign type | Who gets it | Goal | Usually sent |
|---|---|---|---|
| Welcome series | New subscribers or leads | Deliver the promise, introduce you | Automatically, over 1 to 2 weeks |
| Lead nurture (drip) | People who downloaded or signed up | Move to a sales conversation | Automatically, over 3 to 6 weeks |
| Product or service launch | Customers and engaged leads | Awareness and early sign-ups | Once, plus a follow-up |
| Event or webinar | A target segment | Registrations and attendance | Invite, reminder, replay |
| Promotional offer | Engaged contacts | Sales within a deadline | Two or three sends |
| Re-engagement | Contacts with no clicks in months | Win back or remove | Two or three sends, then suppress |
Ongoing newsletters aren’t campaigns in this sense, but each issue benefits from the same discipline: one main idea and one clear next step. For the channel as a whole, see email marketing.
Why campaign planning matters
Mailbox providers watch how people react. Gmail asks bulk senders to keep spam complaints below 0.30%, support one-click unsubscribe and authenticate their domain (Google Workspace Admin Help). Sending the wrong message to the wrong segment raises complaints and hurts every later send, not just this one.
Myth vs fact
- MythSending to your whole list gets the most results.
- FactUntargeted sends raise unsubscribes and complaints, which can push future emails into spam. A smaller, relevant segment often brings more total conversions over time.
An example from our work
Every campaign we write starts with a one-line brief: who it's for, the one thing we want them to do, and what we'll leave out. If the brief needs two calls to action, it's two campaigns. I'd rather send a short email to a small, engaged segment than a long one to the whole list, because a burst of complaints follows you into every send after it.
How to build an email marketing campaign
Seven steps from goal to report
-
Set the goal and the number
For example: 15 demo bookings from a webinar replay campaign.
-
Choose the segment
Pick contacts by behavior and fit, such as attendees who didn't book, in your target industries.
-
Do the funnel math
Work out how many sends, clicks and visits you need (see the example below).
-
Write one idea per email
A specific subject line, a short body, one call to action. Test subject lines with our subject line analyzer.
-
Build the landing page
Match the email's promise exactly. A mismatched landing page loses clicks you've already paid for in attention.
-
Test before sending
Check links, mobile layout, dark mode and plain-text version. Run an A/B test on one element if the list is large enough.
-
Report and learn
Record clicks, conversions, unsubscribes and complaints, and note what you'd change next time.
Worked example: campaign math
Say you want 15 demo bookings from a 3,000-contact segment. Your past campaigns show a 3% click rate and a 10% booking rate from the landing page.
- 3,000 contacts × 3% click rate = 90 visitors per send
- 90 visitors × 10% booking rate = 9 bookings per send
- Two sends to non-clickers gets you close to 15, if the second send performs about as well
If the math doesn’t add up, change the plan before you send: a bigger segment, a stronger offer or a better page. Use your own rates, not industry averages.
Most nurture and welcome campaigns should run on their own once built. See marketing automation.
Frequently asked questions
What is an email drip campaign?
A drip campaign is a set of emails sent automatically on a schedule or after a trigger, such as a guide download. Each email moves the reader one step closer to a decision.
How many emails should a campaign have?
Use as many as the goal needs. Launches often need two or three; nurture sequences usually run four to seven. Stop when replies and clicks drop off.
What makes a good email subject line?
Specific, honest and short enough to read on a phone. It should tell the reader what's inside, not trick them into opening.
How do I check competitors' email campaigns?
Subscribe to their newsletters and download their lead magnets with a work address. Note their timing, offers and calls to action, then make yours more useful rather than copying them.
