In this episode of the "Send It" podcast, host Jimmy Kim and co‑host Chase Diamond dive deep into email deliverability for e‑commerce retention marketing. They start by explaining why deliverability matters – without inbox placement, any copy or offer is wasted – and debunk common myths about Gmail’s Promotions tab, showing it is simply a categorisation rather than a spam folder. The conversation then moves to the technical underpinnings that Gmail and other ISPs evaluate: DKIM, SPF, DMARC, domain reputation, link destinations, spam‑trap detection, and blacklist checks (e.g., Spamhaus). They describe how Google’s Postmaster Tools provide real‑time reputation data and why similar tools from Yahoo and AOL are emerging. Practical testing methods are shared, including creating “seed” inboxes that mirror a brand’s audience mix and monitoring where messages land (Primary, Promotions, Spam). Warm‑up strategies are detailed – start with 1‑1,500 contacts, use a 1.4× daily ramp, layer active and inactive segments, and avoid sudden volume spikes. They stress the importance of breaking down metrics by top‑level domain (TLD) to spot delivery issues. The episode concludes with ten actionable tips covering sender name, subject‑line hygiene, emoji and punctuation use, link authenticity, image‑to‑text ratio, alt‑text, spam‑trigger words, clean footers/unsubscribe, and continuous testing. Throughout, Jimmy and Chase blend technical insight with a conversational, enthusiastic tone, positioning deliverability as a controllable “algorithm” that marketers can master.
