Choose an opt-in method and plan the page and email a new subscriber sees right after signing up.
Choose double opt-in for most public signup forms. Whichever you choose, make sure a new subscriber sees a clear message and gets what they asked for straight away. What happens in the first few minutes after signup shapes how a person treats your emails afterwards.
Picture it from the other side. You fill in a form on a website and press the button. The page reloads. There is no message and no email, so you can't tell whether it worked or whether you should try again. A week later a newsletter arrives from the company. You've forgotten signing up, so you mark it as spam.
There are two decisions behind that experience: how a person gets onto your list, and what they see right after they click.
Single opt-in adds the person to your list as soon as they submit the form. It is one step. Double opt-in sends them an email after they submit the form, asking them to confirm by clicking a link. They join the list only after they click. Some tools call double opt-in "confirmed opt-in". Every email tool supports both, and the setting is usually a single switch on the form or the list.
Single opt-in gives you a bigger list, because some people never click the confirmation link. They miss the email, it goes to spam, or they get distracted. Each of those is a subscriber double opt-in would have lost.
Double opt-in gives you a cleaner list:
Typo addresses never get in. Someone at "gmial.com" cannot click a confirmation link. Fake addresses typed just to get past a form never confirm. Bots that fill in forms automatically do not click links in emails. It keeps out spam traps, which are addresses inbox providers use to catch careless senders. Lesson 3.4, "Clean your list before it costs you", covers these properly. It gives you a stronger consent record of the kind described in lesson 1.2, because you can show the person confirmed from their own inbox.
The trade-off is list size against list quality. A smaller list of confirmed people tends to open, click and reply more, and that engagement helps your mail reach the inbox. Module 3 explains how.
As a rough guide, double opt-in suits most small businesses, especially when the form is public, gets traffic from ads, or has had bot signups before. Single opt-in can make sense where you already trust the address. One example is a checkbox at checkout, where the customer has just typed the same address to get their receipt.
Priya runs a maths tuition centre and offers a heuristics checklist as her lead magnet. She chose double opt-in for her website form because she had seen fake signups before. Mei Ling has an order form with a marketing checkbox. She uses single opt-in there, because customers type their real address on that form to get their order confirmation.
Once you've decided, turn the setting on with the switch on your form or list.
After pressing the button, the person lands on a page or sees a message. This is the thank-you page. Most businesses leave the email tool's default "Thanks for subscribing", which wastes the moment when the person is paying most attention. Replace it with words that answer the three questions the person has: Did it work? What happens now? Where is the thing I asked for?
With double opt-in, the page's most important job is to send people to their inbox to confirm. Name the sender to look for and say the lead magnet comes after they confirm. Then tell them to check their spam or promotions folder if the email hasn't arrived, a line that saves many lost subscribers. Priya's page says, in substance: you're nearly done; check your inbox for an email from Priya at the centre and click the button to confirm; your heuristics checklist comes straight after; if it hasn't arrived in a few minutes, check your spam or promotions folder.
With single opt-in, the page can deliver the lead magnet directly with a download button and tell people what to expect next, including what emails they'll get and how often. For example, a page might say the checklist is below and that the subscriber will also get one email a fortnight with a maths tip for P5 and P6.
Whichever method you use, the lead magnet should arrive immediately. If it turns up the next morning, or the next week when you remember, the person has moved on and may not recognise your name. A confused subscriber is the one most likely to press the spam button.
Most email tools can send the lead magnet automatically. It can go out as a link in the confirmation or welcome email, or appear as a download on the thank-you page. Set it up so it happens without you. That first email is also the opening of your welcome sequence, which module 4 builds in full, and it should arrive while the person still remembers why they signed up.
Two details keep delivery reliable. First, host the file somewhere stable, such as your own website or the email tool's file storage. Avoid a personal cloud folder, because you might change its sharing settings later. Second, send the delivery email from the same sender name you will use for the newsletter, so the name people learn on day one is the one they keep seeing.
In the activity below you will choose single or double opt-in for your own list, write one sentence on why, and draft the words a new subscriber sees on the page straight after they sign up.
