The points below cover the most common pitfalls and the practices that keep your campaigns landing in the inbox. ## 1. Don't purchase contact lists Purchased lists violate GDPR, which requires explicit consent for any marketing email — including emails to business addresses. eMarketeer bans purchased lists in the customer contract for the same reason. Purchased lists also hurt deliverability. Contacts who never signed up have the lowest engagement rates, and major mailbox providers monitor engagement closely. Large sends with few opens reduce your chances of reaching the inbox in future campaigns. Expect bounces and spam complaints on top of that. Purchased lists are also the main source of spam traps — old email addresses that providers convert into traps to detect senders with bad acquisition habits. Hitting one can get you blacklisted instantly. ## 2. Send campaigns from a custom domain Trust starts with the from-address. If the email shows your corporate logo and content but comes from an unrelated domain, recipients notice. With fraudulent email everywhere, the from-domain is one of the first things people check. A custom domain (yourcompany.com) builds sender reputation over time and improves the chance of landing in the inbox. In eMarketeer you can [set up your own email domain](broken://pages/IC60KxnBA16qsuFPFCKb) for sending. ## 3. Clean your contact list regularly Some contacts never unsubscribe but also never open. Keeping unengaged contacts on your list drags down open rates and skews your campaign analytics against your most loyal audience. Mailbox providers like Gmail, Yahoo, and Microsoft monitor engagement. Low engagement makes them less likely to deliver future campaigns to the inbox. eMarketeer excludes non-engaged contacts from send-outs by default (optional). * Non-engaged contacts are those who started receiving emails six months ago or longer, received six or more emails in that period, and never opened or clicked. A few ways to handle non-engaged contacts: * Use a journey to capture non-engaged contacts and send a re-engage email. If they don't engage, the journey can remove or unsubscribe them. * Use the contact filter to find non-engaged contacts and put them on a list with less frequent emails — or remove them. ## 4. Send only with legal basis GDPR requires every marketing email to rest on either explicit consent or another legal basis. When relying on consent, it must be explicit, and you must store the text the contact agreed to. eMarketeer captures and stores consent details with history. eMarketeer has two send modes: one that blocks emails to contacts who have withdrawn consent (unsubscribed), and one that also blocks contacts with no legal basis recorded. We recommend the default — blocking both — under Settings, Subscription and send-outs. ## 5. Send welcome emails The welcome email is the single most effective message you can send. Open and click-through rates are far higher than for any other email type. Welcome emails also keep your list clean. A wrong address bounces immediately, and eMarketeer removes it. They reassure new contacts that the signup worked and the information they expected is on its way. They also help you connect. Offering something valuable at the start of the journey lifts click-throughs. ## 6. Make unsubscribe easy Easy unsubscribe protects deliverability. If a contact no longer wants your email but can't find the unsubscribe link, they ignore your sends — lowering engagement — or worse, report you as spam. Always include a clearly visible unsubscribe link. To meet Google and Yahoo requirements, eMarketeer also adds a one-click unsubscribe link to the hidden email header. Many email clients then surface a built-in unsubscribe button. ## 7. Avoid "No-Reply" sender addresses No-reply prefixes don't build relationships, and they violate the CAN-SPAM Act in the United States. Use a real, ideally personal, email prefix that contacts can reply to. eMarketeer does not send auto-replies to the from-address, so a personal sender address will not get flooded. ## 8. Personalize the greeting Personalizing emails with the contact's name or other specific data improves engagement. * Higher open rates — the name in the subject line makes the email feel relevant. * Higher engagement — personalized content feels tailored, not generic. * Higher conversion — addressing the contact's interests lifts results. * Stronger relationships — personalization signals that the contact matters. * Better experience — tailored messages feel more positive and memorable. Use the personalization features in eMarketeer to insert contact card fields into the subject or body. ## 9. Segment your audience Mass sends to your entire list can work occasionally, but campaigns built for specific segments convert better. The Pareto rule applies here too — 20% of customers generate 80% of revenue. The more relevant the email is to the segment, the more engagement and conversion you see. ## 10. Use a matching preheader The most attention-grabbing part of an email is the preview, especially on mobile. Three elements show in the preview: * The from-name — who the email is from. * The subject line. * The preheader. The preheader is a snippet of the first text in the email. A default preheader like "Click here to open this email in your web browser" wastes the opportunity. In eMarketeer you can write the preheader yourself and use it to draw attention to the content. The preheader shows only in the preview, not the body. Consider personalizing it too. --- # Agent Instructions This documentation is published with GitBook.
