5 Aspects to Analyze When Spying on Competitor Emails

When mastering how to spy your competitors’ email marketing strategy, you must pay full attention to these aspects.

1. Subject Lines and Preheader Text

Study how competitors frame urgency, personalization, and curiosity to earn opens from their subscribers. Since this is what people see at first, you can find what the marketing intent is in a nutshell.

2. Send Frequency and Timing

Record how many emails each competitor sends per week and which days or hours they consistently choose. By learning the rhythm, you can discern that your competitor uses this rhythm based on credible data and behavior patterns.

3. Email Design and Layout

Even things like images, typography, white space, and CTAs can tell you what your competitors are aiming for. The reason is that strong layout choices often reflect design decisions that are based on actual campaign performance data.

4. Calls to Action and Promotional Offers

Document the CTA language competitors use, the discount amounts they promote, and the urgency framing they apply to each offer. From here, you can learn the funnel stage each competitor targets most actively across their campaigns.
