Email Marketing Best Practices: Strategies That Convert in 2025
Master email marketing with proven strategies for list building, segmentation, automation, and writing emails that people actually open.
Email marketing delivers $36 for every $1 spent — the highest ROI of any marketing channel. Here's how to do it right.
Building Your List
Lead Magnets
Offer something valuable in exchange for an email address:
- Ebooks and guides
- Checklists and templates
- Free tools or calculators
- Exclusive discounts
- Webinar recordings
Opt-in Forms
- Homepage popup (after 5-10 seconds or scroll)
- Inline forms within blog content
- Exit-intent popups
- Footer signup
- Landing pages for specific offers
Never Buy Lists
Purchased lists have low engagement, high spam complaints, and can get you blacklisted. Build your list organically.
Segmentation
Segment by Behavior
- Purchase history
- Email engagement level
- Website browsing behavior
- Content interests
Segment by Demographics
- Location
- Industry
- Company size
- Job role
Segmented campaigns see 14% higher open rates and 100% higher click rates than non-segmented ones.
Email Automation
Welcome Sequence
- Email 1 (immediately): Welcome + deliver lead magnet
- Email 2 (day 2): Introduce your brand story
- Email 3 (day 4): Share your best content
- Email 4 (day 7): Soft pitch for your product/service
Abandoned Cart Sequence
- Email 1 (1 hour): Reminder with cart contents
- Email 2 (24 hours): Address common objections
- Email 3 (72 hours): Offer a small incentive
Re-engagement Sequence
- Email 1: "We miss you" with best content
- Email 2: Survey asking what they want
- Email 3: Final offer before removing from list
Writing Emails That Convert
Subject Lines
- Keep under 50 characters
- Create curiosity or urgency
- Personalize with the recipient's name
- Test emojis (they can increase or decrease opens)
Body Copy
- One clear goal per email
- Write like you're emailing one person
- Keep paragraphs short (2-3 sentences)
- Use a clear, single call-to-action
Design
- Mobile-responsive templates
- Single-column layouts
- Large, tappable buttons
- Alt text for images
Metrics to Track
- Open rate: Industry average is 20-25%
- Click-through rate: Average 2-5%
- Conversion rate: Varies by industry
- Unsubscribe rate: Keep under 0.5%
- Spam complaints: Keep under 0.1%
Deliverability
- Authenticate your domain (SPF, DKIM, DMARC)
- Clean your list regularly (remove inactive subscribers)
- Use a reputable email service provider
- Avoid spam trigger words
- Maintain consistent sending frequency
Email marketing remains the most reliable, direct, and profitable marketing channel available. Invest in it.

Talk to Our TeamFrequently Asked Questions
What are the most important email marketing best practices?
Focus on permission-based lists, segmentation, personalized and valuable content, mobile-friendly design, and consistent testing. Deliverability and relevance matter more than send volume.
What is a good email open rate in 2025?
Average open rates vary by industry but typically fall between 20% and 35%, with well-segmented lists performing higher. Because inbox privacy features distort open tracking, prioritize click-through and conversion rates as truer signals.
How often should I send marketing emails?
Send as often as you have something valuable to say, commonly once a week to a few times a month for most businesses. Watch unsubscribe and engagement rates to find the frequency your audience prefers.
How do I keep emails out of the spam folder?
Authenticate your domain (SPF, DKIM, DMARC), use a recognizable sender name, avoid spammy subject lines, and keep your list clean by removing inactive subscribers. Strong engagement is the biggest driver of inbox placement.
