Audit SSL certificate expiry and email providers for a list of domains in Python
I built this actor; it's a paid tool on Apify with a free trial credit. Expired certificates still take sites down, and the usual reason is boring: the domain was on nobody's list. Agencies, IT teams and anyone who inherited a pile of client or company domains have the same problem. You don't need a monitoring product to get a first answer. You need one table: domain, certificate issuer, expiry…
The author developed a Python tool to examine SSL certificate expiry dates and email providers for a list of domains. This free tool, part of Apify's paid service with a trial, checks certificate issuance, expiry, days remaining, email providers, and DNS providers. During testing on 24 September 2026, 46 domains were analyzed. Twenty-four used Google Workspace, six Microsoft 365, and three Proofpoint email providers.
The tool identified 12 domains with certificates expiring within 90 days, with the shortest remaining life at 30 days for kyliecosmetics.com and deathwishcoffee.com. The longest expiry was for cnn.com, at 178 days.
