10 Email Marketing Tips to Get Repeat Customers (2026)
SEO and ads bring new visitors, but what brings customers back? Email. A list of people who asked to hear from you is the one marketing channel you fully own, and it still delivers some of the best returns of any channel. But inbox providers are stricter than ever about spam. Here are 10 email marketing tips to win repeat customers in 2026, updated from Eric Gesinski’s original guest post.
Quick answer: Only email people who opted in, set up SPF, DKIM and DMARC for your sending domain, add a one-click unsubscribe, send a welcome series, give useful content rather than constant sales pitches, segment your list, write for mobile with one clear call to action, test subject lines, and use a proper email service such as Mailchimp, Kit, MailerLite or Brevo.

10 email marketing tips
1. Always get permission
Use an opt-in form and never buy lists. Laws such as GDPR in Europe, CAN-SPAM in the US and India’s DPDP Act set rules on consent and unsubscribes. Double opt-in (confirming by email) keeps your list clean and proves consent.
2. Authenticate your domain
Since 2024, Gmail and Yahoo require bulk senders to authenticate with SPF, DKIM and DMARC, offer one-click unsubscribe and keep spam complaints very low. Your email provider shows you the DNS records to add.
3. Send a welcome series
New subscribers are most engaged in the first few days. Send an automatic welcome email with what to expect, your best content and a small offer.
4. Give value, not just sales
If every email is a hard sell, people stop opening them. Share tips, guides, news and stories, and mention offers occasionally. Trust makes the occasional promotion work much better.
5. Segment your list
Group subscribers by interest, purchase history, location or activity, and send each group what’s relevant. Targeted emails get far more clicks.
6. Write for mobile
Most emails are read on phones. Use a single-column layout, short paragraphs, a large button and a readable font size. Keep a plain-text version for readers who prefer it.
7. Repeat your key link
Put your main link near the top and again at the end, ideally as a button. Our tips to increase email click-through rate go deeper.
8. Test subject lines and timing
A/B test subject lines, preview text and send times. Measure clicks and sales, since Apple Mail Privacy Protection makes open rates unreliable.
9. Clean your list
Remove addresses that bounce and people who haven’t opened or clicked in months, after a last re-engagement email. Sending to dead addresses hurts deliverability.
10. Use a proper email service
- Mailchimp: popular all-rounder with automations.
- Kit (formerly ConvertKit): built for creators and bloggers.
- MailerLite and Brevo: generous free plans.
- Self-hosted: tools like Sendy with Amazon SES, which QuickOnlineTips has used, cost very little for large lists but need more setup.
The original post recommended Constant Contact and AWeber, which are still available too.
Grow your list
Add sign-up forms to your blog, offer a useful freebie such as a checklist, and send traffic to a focused landing page.
FAQ
How often should I send marketing emails?
Once a week or once a fortnight works for most blogs and small businesses. Consistency matters more than frequency.
Why do my emails go to spam?
Usually missing authentication (SPF, DKIM, DMARC), high complaint rates, purchased lists or spammy content.
Is email marketing still worth it in 2026?
Yes. Subscribers chose to hear from you, and no algorithm decides whether they see your message.
