Summary
What email marketers say13Marketer opinions
Email marketer from SMTP2GO shares that domain reputation is crucial as it affects deliverability. They recommends consistently sending valuable content, authenticating your email, and avoiding spam triggers to maintain a good domain reputation.
Email marketer from GlockApps explains that warming IPs and domains together requires special care. The first mail should be to engaged users and then gradually increase.
Email marketer from Mailjet explains that domain reputation is crucial for deliverability, especially with ISPs like Gmail. Suggests starting with low volumes of emails to engaged users and gradually increasing the volume while monitoring deliverability metrics to warm up the domain effectively.
Email marketer from Email Geeks suggests that if the IP is sufficiently warmed and a good email sending cadence has been maintained to keep the IP in good standing then you should be good without much worry, but still take caution, and suggests ramping up slowly on new domains just to be safe. Suggests starting at 25 emails on Day 1 and doubling each day after is perfectly fine. Just watch your metrics - bounces should stay below 2% although you can get by with higher. Spam complaints ideally should stay at or below 0.1%. If you unsubscribe rate begins to skyrocket then maybe they are unaware of the transition you’ve made so make sure to be clear on that fact.
Email marketer from Quora says that consistency is key for email sending. Sending emails regularly from your domain helps to establish trust with email providers. Make sure to maintain a consistent sending schedule, even when starting with low volumes.
Email marketer from Email Geeks shares that a domain warm up is definitely needed when changing a domain on a warm IP, but it doesn’t generally need to be quite as painstaking as a full IP warm up. Recommends a gradual migration of the sending domain, starting very small (200 messages or so) and then increasing by 100% each day (or each time you mail) for a week, getting to about 12,000 a day. After that you could increase by 200% each time until everything is migrated over. During the migration, make sure the engagement stats are the same between the two domains - if opens and clicks on the new domain lag significantly behind then pause the ramp-up at the level you’ve got to, and wait until the engagement catches up before moving ahead again.
Email marketer from the Email Marketing Forum shares to warm your domain by ensuring proper email authentication (SPF, DKIM, DMARC) as this builds trust with email providers. It validates that you are who you say you are and reduces the chances of being flagged as spam.
Email marketer from Reddit shares to start with a small number of emails to your most active subscribers. Then, slowly increase the volume each day or week, while monitoring metrics such as open rates, click-through rates, and spam complaints. Engaging content to opted-in subscribers only.
Email marketer from SendGrid explains that building a sender reputation involves establishing trust with ISPs. Recommends a gradual ramp-up of email volume, sending to engaged subscribers, and monitoring bounce rates, spam complaints, and unsubscribe rates to ensure a healthy sender reputation.
Email marketer from Email Geeks seconds the need to definitely warm the domain, stating that many providers put a lot of faith in domain reputation now.
Email marketer from DigitalMarketer explains to isolate a segment of highly engaged subscribers and focus your initial sending on them. These users are more likely to open and click your emails, which sends positive signals to mailbox providers. Track metrics such as open rates, click-through rates, and unsubscribe rates during the warm-up period. If you notice any dips in engagement, pause the warm-up and address the issues before continuing.
Email marketer from EmailOversight shares that to warm up an IP and domain together, you must be consistent with the type of mail you send, and who you send to. Make sure to stay consistent to get the best results.
Email marketer from Email Geeks suggests starting at 500 emails then doubling from there as long as the IP was previously warmed. Suggests using a segment of the most engaged audience to do a proper warm up if you’re able to identify them.
What the experts say4Expert opinions
Expert from Email Geeks shares that the more/better you can warn customers about a domain change, the less confusion will happen, and the fewer spam complaints you’ll get, and deliverability will be less likely to suffer.
Expert from Word to the Wise (Laura Atkins) explains that domain reputation is essential when warming an IP address. Domain reputation matters; if you're only changing the domain, the IP's existing reputation provides a boost, allowing for a faster ramp-up. Start by sending to engaged users to ensure positive engagement and then gradually increase the volume while watching for negative signals. If your engagement is good, you can increase volume more aggressively.
Expert from Email Geeks confirms that domain warming is indeed a thing now. Suggests coordinating with the SFMC deliverability team to have both domains active for a period of time, and potentially even ensure that multi-bounce domain is enabled, so that you can have the return-path (SPF) domain match the from domain in both cases.
Expert from Spam Resource (Steve Linford) explains that when moving to a new domain on an existing IP address, warming is still necessary, but less intense than a completely new setup. Start by sending to your most engaged users, monitor engagement, and gradually increase volume. Don't immediately blast your entire list. Prioritize users who frequently open and click your emails, as these interactions signal positive engagement to ISPs.
