Frequently asked questions
What email marketing platform should I use?
The right platform depends on your needs. For creators and small businesses: MailerLite (best free tier) or Kit (best for creators). For e-commerce: Klaviyo (best for Shopify integration). For B2B SaaS: Customer.io or ActiveCampaign (most automation depth). For sending transactional emails from a web app: Resend or SendGrid. This course covers MailerLite in depth as the recommended starting point, with comparisons to alternatives.
How do I build an email list from zero?
List building starts with a compelling reason to subscribe — a content upgrade, free tool, course, or exclusive content that delivers enough value to earn an email address. Most effective channels: a high-intent lead magnet on your website, an exit-intent popup, social media promotion, and a referral loop within welcome emails. Growing a small, high-quality list of 500–2000 engaged subscribers is far more valuable than a large disengaged one.
What is email deliverability and how do I protect it?
Deliverability is the percentage of your emails that reach the inbox rather than spam. It depends on: sender reputation, authentication (SPF, DKIM, and DMARC records), engagement rates (opens and clicks), and list hygiene (removing bounced and disengaged addresses). Sending to an unengaged list destroys deliverability. This course covers the technical setup and sending practices that protect inbox placement.
What is an email automation sequence?
An automation sequence is a series of emails sent automatically when a subscriber takes a specific action — signing up, purchasing, or abandoning a cart. The most valuable sequences are: welcome series (sent to new subscribers over the first 1–2 weeks), onboarding series (for new product users), re-engagement series (for inactive subscribers), and post-purchase series (cross-sell and review requests). Automations run 24/7 and compound in value over time.
What open rate and click rate should I aim for?
Reasonable targets for engaged lists: open rate 25–40%, click rate 2–5%. These numbers have shifted with iOS privacy changes that inflate open rates, so focus on click rate as a more reliable engagement metric and on downstream conversions as the ultimate measure. A small, highly engaged list with 40% open rates is worth far more than a large list averaging 10%.
