eCircle's 4 pillar concept for maximum email deliverability
Ensuring email deliverability and emails that are correctly displayed in the recipients’ inbox is one of our core areas of expertise. A closed concept, based on 4 pillars, guarantees that emails are delivered safely and faultlessly into the recipients’ inbox passing spam filters and blacklists.
Pillar 1 – Deliverability starts with the email marketing software
- Our email marketing software’s automated address control and comprehensive bounce management system minimises the main deliverability risks
- Comprehensive blacklist management prevents spam complaints
- Time and volume controlled send out and an email syntax check complement the feature package
Pillar 2 – ISP relations, whitelisting and industry standards
- We have our own team of Project Managers dedicated to building up good relationships with all major ISP’s and FreeMail providers at an international level
- eCircle is a member of the Certified Senders Alliance (CSA) - the first Europe-wide whitelist for professional email senders
- Our participation in the Sender Score Receiver Alliance, an ISP relations program from Return Path, guarantees you further access to all important ISPs across Europe
- At an international level, eCircle gets involved in all important deliverability and anti-spam initiatives (e.g. the MAAWG) to represent your interests as a commercial email sender, setting standards for clean and safe email marketing
Pillar 3 – Proactive control and warning systems prevent blockings and false positives
- Ongoing monitoring of test accounts on the safe delivery of your emails
- An IP block alarm is checking all relevant public blacklists
- In addition, with the Sender Score Monitor from Return Path you can see at a glance if there is one of the major ISPs or FreeMail providers blocking or filtering your emails and if the graphics are displayed correctly
Pillar 4 – Individual analyses on clients demands
- Individual analyses for companies which are wishing to see an improvement of their newsletter in terms of popular anti-spam measures
- The content and classification of your emails will be verified with all the major ISP’s
