Identifying bugs can be done through several methods: - Email Previews: Use tools like Litmus or Email on Acid to preview how your email renders across different clients and devices. - Link Testing: Manually or automatically check all hyperlinks to ensure they direct to the correct pages. - Content Review: Have multiple team members proofread the email for any typos or grammatical errors. - Deliverability Testing: Use tools like MailTester to check if your email will land in the inbox or spam folder.
