Great emails are worthless if they land in spam. Deliverability comes down to sending from a verified domain and treating your list well - both straightforward once set up.
Verify your sending domain. On onboarding we help authenticate the domain you send from (the behind-the-scenes records that tell inboxes your mail is legitimately yours). Unverified domains get filtered fast, so this is the single most important step.
Keep your list clean. Email people who expect to hear from you, remove hard bounces, and let long-inactive contacts go - a small engaged list beats a big stale one. Your genie handles unsubscribes automatically to protect your reputation.
Write like a human. Avoid all-caps subject lines, spammy words, and walls of links. A plain, personal email from a real business outperforms a flashy 'blast' both on deliverability and replies.
Tip: warm up gradually. If you've never emailed your list from the new system, start with your most engaged customers before mailing everyone - it builds sender reputation and keeps you in the inbox.
