To ensure that your eMails reach your recipients reliably, there are a few simple points that you can consider to support the deliverability of your eMails.
Make sure that your eMails are not sorted out by a spam filter, that you only send your eMails to addresses whose recipients can and want to receive your eMails, and that your eMails are also technically delivered to your recipients.
10 tips for better delivery
- Use a trusted and unique email sender address and email sender names that are associated with your organization, whose mailboxes you have access to and are allowed to use.
- Use an SPF and DKIM record to verify and legitimize the authenticity of your sender addresses. SPF and DKIM are two methods to verify that the sender of an email is authorized to send an email at the sender's address, even if the sender's IP address does not match the IP address of the sender's domain.
- Formulate a meaningful subject so that your eMail is not caught by a spam filter. Avoid excessive use of capital letters, exclamation marks, special characters, symbols and terms that are suspected to be spam.
- Avoid spam-suspicious words in your eMails that could trigger a spam filter. Test your eMails before sending them to detect and avoid possible spam words. Avoid words such as ONLY NOW, buy, Viagra, etc. Words of this type can trigger spam suspicions.
- If possible, only use links to pages on your own servers where you know exactly what content can be accessed, or link only to domains with trustworthy content.
- Do not include file attachments in your emails. These can possibly lead to a higher spam rating and unsubscribe rate.
- Allow recipients to easily unsubscribe from your emails via an unsubscribe link ({$REVOKE_URL}) if they no longer wish to receive your emails.
- Only use email addresses for sending emails that you are sure are valid and reachable. Addresses that can cause hardbounces over a longer period of time should be deleted from the pool. Also, only send to email addresses from which you have permission to advertise (permission: double opt-in). Purchased e-mail addresses should never be used for sending. Check the profile list in the pool for invalid or outdated profile data. Delete profiles with incorrect or faulty data or profiles that exist multiple times in the pool (duplicates).
- Create a list of blocked contacts (blacklist) to prevent your emails from being sent to addresses (possibly outside companies) that you do not want to receive your emails from.
- Spread out the e-mail transmission over a longer period of time (deliverability optimization) to avoid thousands of e-mails arriving at an e-mail provider within a short period of time, possibly activating spam filters.
Under the tab Transmission you can set how many e-mails should be sent per hour.
CSA certification
The Certified Senders Alliance (CSA) certifies senders of newsletters and other emails, so-called bulk mailers, as reputable providers. To be certified, senders must meet strict legal and technical quality standards. The CSA is a positive list project jointly launched and operated by the German Dialog Marketing Association (DDV) e.V. and eco - Association of the German Internet Industry. As the manufacturer of the e-mail marketing automation solution Evalanche, our company has been on the whitelist for almost 10 years. On this whitelist IP addresses of email senders are registered, who have committed themselves to send email only to recipients who have given their permission. The Certified Senders Alliance provides one of the most frequently used whitelists for providers in German-speaking countries.
