DMARC for Recruitment - Quinset

Email Delivery: The State of Recruitment Agencies

Trust is a recruitment company’s most valuable asset. Consistent email delivery, free from technical glitches or deliverability issues, protects your brand reputation. It showcases reliability and professionalism, reinforcing your standing in the competitive recruitment landscape.

Effective email delivery expands the outreach potential of recruitment campaigns. Whether reaching out to passive candidates or maintaining an active dialogue with clients, reliable email delivery ensures that your messages are not lost but instead make a meaningful impact.

Our researchers assessed nearly 500 recruitment companies in the UK, looking at their email domain settings to ascertain their maturity, and ability to carry out successful email campaigns and day-to-day interactions.

There are many aspects to getting email delivery right, with DMARC being a key tool in the fight against spam filters, protecting the reputation of your domain and aide in fixing email delivery issues.

Only half the agencies assessed had implemented any form of DMARC, of which only 20% had a mature configuration that protected them and gave them insights into their email delivery.
