If you have sent a test email or a newsletter and found it in SPAM folder, there may be a few reasons for that. Make sure your emails are awesome and don't look spammy.

Check, if you are using your own domain for sender's email

An example - "contact@myshopsdomain.com". You should be doing that. Email service providers (such as Yahoo, Gmail, AOL and others) are very picky if you are sending newsletters using their domains - @yahoo.com, @ymail.com, @gmail.com, @aol.com, etc. In most cases, they will put your newsletter in SPAM folder or reject it. In conclusion - don't use myemail@yahoo.com. Use contact@myshopsdomain.com instead. Read more about DMARC policy. 

Check if your newsletter has enough text content

Don't put only images in your newsletter, mix it with some text. Some spam filters check text-to-images ratio.

If you are using custom domain, it might have some bad reputation from the past

Have you ever tried to send a lot of same emails directly from your inbox trying to promote your products (before you started using Omnisend)? Then it is possible that your domain's reputation is compromised. You can check it here. Just enter your domain (i.e. myshopsdomain.com) and click "Blacklist check" to check if it is blacklisted.

Make sure your content does not look spammy

Take a look below at some common mistakes that should be avoided:

  • Excessive use of exclamation points!!!!!!
  • Using phrases like “Click here!” or “Once in a lifetime opportunity!”
  • USING A LOT OF ALL CAPS IN SUBJECT LINE AND IN BODY TEXT. Don't do that (especially in subject lines).
  • Sending a test to multiple recipients within the same company (your colleagues). It's possible that company’s email firewall will assume it’s a spam attack.
  • Hash-busting: Inserting random characters in the subject line or content to fool spam filters, e.g. “F.ree. p.r!z.e”
  • Be careful with words associated with the language of sales. You can still use them but don't use them too often. If overused, they may trigger spam filters and route your emails to junk folders. Risky words include: “prize”, “free”, “bonus”, etc.

Some good practice:

  • Don't purchase mailing lists. They usually contain a lot of spam traps and inactive emails address. These two factors will harm your domain's reputation. If your newsletter campaign will get more than 4.0% bounce rate or more than 0.1% complaint rate ("marked as spam"), your account on Omnisend will be terminated.
  • Don't use old or stale mailing lists. If you are migrating to Omnisend from other email service provider, import to Omnisend only those subscribers who were active (opened or clicked your newsletters) in last 6-12 months. Subscriber engagement is a huge part of getting emails into the inbox, when an ISP (internet service provider) sees low engagement rates they will often begin to bulk the campaigns to the spam folder. Then they will block the domain and IP addresses used to deliver the campaigns.
