Did you know that up to 20% of all email ends up in the spam folder? While email marketing continues to evolve, the goal remains the same – to stay out of the spam folder and deliver your message. Unfortunately, the rules are constantly changing, making it difficult for marketers to know how to shape each message.
Let's take a closer look at how to stay out of the spam folder in 2018.
Choose the Right Email Service Provider (ESP)
Great advice, but how do you know which ESPs are considered "good" ones? Email service providers are judged on the reputation of the IP (Internet Protocol) addresses and domains of their clients. To ensure you're using a quality ESP, check that they only allow users to send solicited emails, and make sure they ban spammers from their platforms. These are the ESPs with greater credibility with mailbox providers.
Authenticate Your Email Sending Domain
Email authentication (aka email validation), is exactly what it sounds like – it verifies the authenticity of an email sender. This is important to set up, because validated email senders are more likely to stay out of the spam box. Your IT contact should authenticate your email sending domain with DKIM (DomainKeys Identified Mail). According to Hubspot, “DKIM (Domain Keys Identified Mail) email authentication is used to verify a sender's identity. Part of this process involves your domain host validating the email domain.” For help setting up your DKIM, check out this MailChimp blog
ONLY Send Solicited Emails
It's tempting… you see juicy headlines reading "Targeted Leads" and "Triple Your Response Rate" and all sorts of other false promises. If you want to stay out of the spam folder, do not, we repeat, do NOT buy purchased lists filled with unsolicited email addresses. This is even more important to Canadians since the new CASL rules came into play last year. You do not want to be sending unsolicited emails. Period.
Keep it Clean
We're not just talking about keeping your lists clean (although that's important, too). We're talking about keeping your emails clean – free from profanity, misleading subject lines, and anything that may be considered offensive. Also steer clear of certain buzz words that will inevitably land your message in the spam folder, such as free, promo, surprise, winner, guarantee, and so on.

Ask to Be Whitelisted
Tried and tested, this one still remains one of the best ways to stay out of the spam folder. Most spam filters allow you to whitelist certain senders. So when your new subscribers give up their contact info, be sure to tell them how to add your email address to their whitelist to avoid future emails from winding up in the junk box.
Better open rates and stronger click through rates (CTRs) mean better deliverability. To maximize open rates, send your message at the right times. People check their email most often during 8-9am and 3-4pm EST, Sunday through Thursday. A great way to take advantage of this is to use a tool like HubsSpot Smart Send, which times the send of your messages based on the recipient's time zone.
To increase CTRs, remember to include a call to action in your email. People need to be told what to do next. When you include a strong call to action, you create a strong click through rate (improving overall deliverability), but more importantly, you're helping your prospects take action toward becoming a customer—and that is, after all, the ultimate goal of your inbound marketing strategy.
