It can be really frustrating to have set up a campaign only to have your clients report that your email has gone into their spam folder. Here are some tips on how to avoid that trap.
1. Use Permission Marketing Techniques
Try to make sure you've allowed your clients the opportunity to agree to be on your marketing list. You can take it a step further at the point of subscription and ask to be placed on their whitelist.
Always make sure you have an Unsubscribe link in your email, and include your physical address (that's why we ask you to set this up in your Account details when creating your Boma account). We want your emails to go to your clients!
2. Be careful around links, phrases and your words
Spam filters look for emails that are "sneaky" and try to stop them going to your client's inboxes. That means they often look for spam trigger words like "amazing" or "great offer". Unfortunately, there is no complete list of spam trigger words, and this might not mean they fall into a spam filter anyway, but it's useful to be careful around what you're saying.
A spam filter is trying to remove commercial advertisements and promotions. So generally, words that are common in such emails should be avoided or used sparingly.
Phishing emails are designed to steal your identity by getting you to click on a fraudulent link. You want to avoid using phrases that are common to phishing attacks. Keep your links coming from your website so that spam filters can match the URL with your business name if possible.
3. Use Spam Checkers Before Sending Your Emails
Before sending emails out to your entire list, it’s worth the time to utilize a spam checking service.
SpamAssassin is a great place to start. If you prefer to avoid downloading any software, you can send email to the IsNotSpam.com service and they will also check a few other items important to email deliverability. Alternatively, ProgrammersHeaven.com uses a form-based solution to test your emails.
4. Be Compliant with the CAN-SPAM Act and GDPR
This is easier than it sounds! This means you need to keep an eye on your subject lines. Try to make sure they reflect what is in the body of your email.
Keep an eye on your header information as well - and the snippets that email systems use to preview emails for your clients.
If you are sending promotional material, let your client know that it is a promotion - making them think it is just a newsletter can cause your clients to put your emails into spam on purpose - and that harms your emails.
As per number 1, give your clients the opportunity to unsubscribe, and make sure your address and "from" fields are included.
5. Maintain a Good Text to Image Ratio
Images can affect deliverability, with purely image emails being seen as purely marketing or sales information. Try to minimize the amount of images in your emails.
Do include your logo (we do that for you) because that helps your clients remember you better.
6. Don't use purchased email lists
Please use an opt-in process with your clients and their emails, and do not buy lists from email brokers. Even if your intended recipients are already your customers or colleagues, do not send promotional emails without getting permission first. Consider adding a signup form to your website or giving customers the option to sign up for your list when they make a purchase from your store.
7. Avoid Large Attachments and Certain Attachment Types
In general, .jpg, .gif, .png and .pdf attachments are safe to send, provided you include some content in the email as well. But it is not recommended to include anything as an attachments in a marketing email. Linking to them from the email is fine.
However, executable attachments such as .exe, .zip, .swf, etc. should be avoided entirely. Generally, you should not send attachments to people on your list who are not expecting them.
8. Authenticate your email with SPF, DKIM, and DMARC
You can also authenticate your email sending, this is quite technical but helps with deliverability as it shows email receivers that your email is coming from a known source and therefore is more likely to be trusted and less likely to be identified as spam.
9. How often do you send?
The last thing you might also want to consider is frequency. If you email every single day, your clients are more likely to think you are spamming them. Try to think about how often you want to send them a message about what you have going on - whether it is a weekly newsletter, a monthly update or a bi-weekly promotion.
