Bulk HTTP to HTTPS redirect checker: do plain http addresses reach HTTPS?
In short: Paste a list of domains and request each plain http address: see whether it ends on HTTPS, the redirect status and every hop, as a CSV. Limit: Only the root address of each domain is requested.
A bulk HTTP to HTTPS redirect checker requests each domain's plain http address and follows the redirects. Paste up to 100 domains, or 500 after a free Google sign-in; each row says Redirects to HTTPS with the status code, Stays on HTTP, or HTTPS only with nothing on port 80, and lists the hops. Download the CSV.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. Check your list free nowSee pricing

Cleaning a list of company websites before outreach?
- Paste the domains here: 100 a run, or 500 after a free Google sign-in. Filter to the flagged rows and download the CSV.
- Upload or paste it at /verify. Every address gets a live mailbox check, and the first 100 email checks are free with a Google sign-in, no card.
How do I check HTTP to HTTPS redirects on many websites?
- Paste up to 100 domains, or 500 after a free Google sign-in, one per line; emails and URLs work too. You can also upload a CSV.
- Press Check HTTP to HTTPS redirects. Each domain's http address is requested once and its redirects followed, five at a time.
- Read each row: where the http address ends, the first redirect's status code and the hops.
- Filter to the flagged rows and download the CSV.
Example
- You enter
- Three sites:
acme.example(301 to HTTPS),globex.example(302 to HTTPS) andinitech.example(answers 200 on plain http). - You get
- acme.example: Redirects to HTTPS (301). globex.example: Redirects to HTTPS, temporary (302). initech.example: Stays on HTTP. Download the CSV.
- Limits
- Up to 100 a run without an account and 500 when signed in with Google, counted over a minute. 10 sites a request; one request per site from our server, no cookies, nothing stored.
What counts as a good redirect?
A permanent redirect (301 or 308) from the http address to HTTPS, in one or two hops. A temporary status such as 302 or 307 is flagged because it tells clients the move may be undone; the status codes are defined in RFC 9110.
Stays on HTTP means the plain address answered without moving to HTTPS.
What does the tool not check?
It follows up to five redirects and reads the final address. It doesn't check certificates (use the bulk SSL checker) or HSTS (use the bulk HSTS checker).
For a plain live-or-down read of every site, use the bulk website status checker.
What do you do with the flagged rows?
Fix the redirect at the web server or CDN, or keep the rows as prospects for web work. See the whole chain with the bulk redirect checker.
Before you email contacts at these companies, verify the addresses.

Common questions
- How do I check if http redirects to https?
- Paste the domains into a bulk HTTP to HTTPS redirect checker like this one. It requests each plain http address and follows the redirects.
- Is this redirect checker free?
- Yes. 100 domains a run without an account, 500 after a free Google sign-in, with no card, and a CSV download.
- Is a 302 redirect to HTTPS a problem?
- It works for visitors, but 301 or 308 is the usual choice for a permanent move, so it is flagged.
- What does HTTPS only mean?
- Port 80 didn't answer but HTTPS did, so typing http:// gives an error rather than a redirect.
- Does it check the certificate?
- No. Use the bulk SSL checker.
- Does it check my contacts' email addresses?
- No. Verify them separately at /verify.

A tidy list can still be full of dead addresses.
Extracting, deduplicating and syntax checks all work on the text of an address. None of them can tell whether the mailbox exists. Only the server that hosts it can answer that, through an SMTP check, and that is what the paid product does.
- Upload the cleaned file as it is: CSVs up to 100,000 rows
- A real SMTP mailbox check on every row, with catch-all detection
