include:zcsend.in – Zoho Campaigns (India data centre)
Short answer: include:zcsend.in lets Zoho Campaigns (India data centre)'s mail servers pass SPF for your domain. It costs 1 of the 10 DNS lookups SPF allows (checked live).

| Record now | v=spf1 ip4:103.103.198.0/24 ip4:169.148.137.0/24 ip4:103.103.199.0/24 -all |
Do you need it?
Often not. From our Zoho Campaigns setup guide: That is the default data centre. EU accounts use include:eu.zcsend.net, India include:zcsend.in, China include:zcsend.net.cn. Zoho Mail for your mailboxes is separate (see the Zoho Mail guide): both includes go in the same record.
If you added include:zcsend.in only because an old article said so, it may just cost lookups. Send a test email through Zoho Campaigns (India data centre) and see which domain SPF is checked for.
Who uses it
In our scan of top websites on 23 Oct 2026:
- 0 of the 2,214 world's top-3,000 sites that publish SPF (0.0%)
- 33 of the 1,961 India's top-3,000 sites that publish SPF (1.7%)
- 0 of the 428 Indian government sites that publish SPF (0.0%)
Add it the right way
- Keep one SPF record per domain:
v=spf1 include:zcsend.in ~all, plus your other senders in the same record – SPF generator. - Stay under 10 lookups in total; every include counts, nested ones too.
- SPF alone isn't enough for Gmail, Yahoo and Outlook: turn on DKIM and publish DMARC.
Check your domain
After the fix, send a test email to see SPF, DKIM and DMARC pass on a real message, then keep an eye on it: free DMARC monitoring shows every service that sends mail as your domain and which ones fail, in plain English.
