What does an email deliverability service actually fix?
An email deliverability service fixes inbox placement: it finds why a receiving server accepts your mail but files it as spam, then repairs the DNS, the sender reputation, the list or the sending pattern. Acceptance and placement are different outcomes. A successful SMTP handoff only means Gmail, Yahoo or Outlook took the message; placement is whether it appears where a person reads mail.
In India the typical setup behind a deliverability problem is your own domain, a mailbox your staff use daily, and DNS you control. Before hiring anyone, confirm you are troubleshooting the right product. A business mailbox on your domain, a transactional relay for password resets, and a bulk sender for newsletters are three different purchases that fail in three different ways.
- Authentication failures — missing or broken SPF, DKIM or DMARC records, the most common cause for small Indian domains.
- Reputation damage — a shared IP with a poor history, or your own IP flagged after a compromised mailbox.
- List problems — addresses that never opted in, stale inboxes that have turned into spam traps.
- Volume patterns — a new domain or IP suddenly sending like a spammer instead of warming up.
How do you set up SPF, DKIM and DMARC before calling anyone?
Publish one SPF TXT record, switch on DKIM in the mail panel, then add a DMARC record at p=none and read the reports for a few weeks before tightening anything. This is the DNS work every deliverability engagement starts with, and on a normal domain it costs nothing but an hour. Check your current records first with the email authentication checker.
- One SPF record. Include only servers that genuinely send for you. Two SPF records invalidate both, and extra includes can push you past the 10-DNS-lookup limit, which fails the check silently.
- Enable DKIM. The mail panel generates a public key; publish it under the selector the panel names. The selector on the message must match the name in DNS.
- Add DMARC at p=none. This reports failures without blocking mail. Move to quarantine or reject only after legitimate mail passes both SPF and DKIM alignment.
- Wait out the TTL. Re-test only after the record's TTL has expired, or you will judge yesterday's DNS.
If reports show mail passing authentication but still landing in spam, the problem is reputation or content behaviour — that is the stage where paid help starts to earn its fee. DNS mechanics are covered in more depth in the guide to checking a domain's DNS records.
What do Gmail and Yahoo require from bulk senders in India?
Google and Yahoo apply extra requirements once a sender reaches roughly 5,000 messages a day to their users: SPF, DKIM, a DMARC policy, and a From domain that aligns with one of those checks. Mail people subscribed to also needs a working one-click unsubscribe, and the spam-complaint rate should stay under 0.3%.
The threshold is not permission to skip DNS at lower volume. Ordinary staff mail from a small Indian business benefits from the same authentication, and the 5,000-a-day volume can arrive quickly once a campaign goes out. Two free dashboards show how the big providers score your domain: Google Postmaster Tools and Microsoft SNDS. They report reputation; they do not replace the records and they will not clear a blocklist for you.
Should you check blacklists before rewriting your emails?
Yes — run the sending IP and domain through an email blacklist check before touching the subject line, because a listing on a major blocklist spam-folders or rejects mail that is perfectly authenticated. The detailed walk-through of causes and removals is in the email blacklist guide.
The usual reasons behind a listing are a compromised mailbox sending from your account, an open relay, or a list of addresses that never asked for your mail. Fix the cause first: reset passwords, close the relay, stop sending to that list. Requesting delisting while the behaviour continues puts the IP straight back on the list, usually with less patience the second time.

How do you warm a domain or IP — and where does cold email belong?
Warm a new domain or IP by sending only mail recipients expect, in small numbers, and raise volume only while acceptance stays high and almost nobody marks it spam — typically over two to four weeks. There is no history for a provider to consult on day one, so the pattern you set becomes the reputation.
Prospecting traffic must not share that reputation with the domain your clients write to. A common Indian setup keeps cold campaigns on a spare domain with its own dedicated IP — the cold email VPS guide explains the separation. Keep billing addresses, support conversations and invoices on the company domain, untouched by campaign volume.
Mailbox, transactional or bulk — which product does each email need?
Match the tool to the mail: staff correspondence in mailboxes, password resets and receipts on a transactional relay, opted-in newsletters on a bulk sender with unsubscribe, and cold prospecting on a separate domain entirely. Buying the wrong layer produces deliverability complaints no consultant can fix.
| Mail you send | Where it should live | What "done" looks like |
|---|---|---|
| Staff and client replies | Mailboxes on your own domain | A test from the new address lands in a Gmail inbox you control |
| Password resets, receipts | A transactional relay your app calls | The app's From domain passes SPF or DKIM |
| Opted-in newsletters | A bulk sender with one-click unsubscribe | Complaints stay under 0.3% and unsubscribes work |
| Cold prospecting | A spare domain with its own IP | The company domain never appears on the campaign |
WebJi® hosts the first row: business email on your domain runs ₹2,520 to ₹14,400 a year before 18% GST, as read from the WebJi® billing table on 30 October 2026 — five mailboxes at 5 GB each at ₹2,520 a year is the entry row, and the top cloud row is ₹14,400. That price is the mailbox, not a deliverability retainer. For the subscription-suite side of the decision, the Zoho vs Google Workspace comparison and the Google Workspace vs Microsoft 365 matchup carry the plan detail.
When is it worth hiring a deliverability specialist?
Hire a specialist when authenticated mail still misses the inbox, a blocklist you cannot clear is rejecting you, or complaint rates on a genuine campaign keep climbing — not merely to create an address on your domain. That last job is a mailbox, and a business email setup guide covers it without a retainer.
Be clear about what WebJi® is and is not. WebJi® has hosted sites and mail since 2005, serves about 99% of clients online from Shop #27, Ajmer Road, Tagore Nagar, Jaipur 302021, and answers support@webji.services in Hindi and English with an average first reply under 60 minutes. It hosts the mailbox and publishes the DNS for SPF, DKIM and DMARC. It is not a transactional email API, a lead database or an inbox-placement consultancy; a specialist engagement, where one is needed, is quoted by email before you pay, and invoices add 18% GST.
Frequently asked questions
Why do business emails land in spam in India?
Usually the DNS is incomplete, the sending IP carries a poor history, or the list includes people who never asked for the mail. Gmail and Yahoo add bulk-sender rules once volume is high. Content and subject lines are rarely the first cause; check authentication and blocklists first.
What does business email hosting cost before GST?
The WebJi® billing table, read on 30 October 2026, runs from ₹2,520 a year for five mailboxes at 5 GB each to ₹14,400 a year for the top cloud row, before 18% GST. That is mailbox hosting with DNS for SPF, DKIM and DMARC — a deliverability audit is a separate, quoted job.
Should I buy a dedicated IP for email?
Not for ordinary staff mail. A shared mail platform is normal when the host maintains it and keeps its IPs clean. A dedicated IP matters when you send enough to need your own reputation or your own server delivers the mail. Ask before paying for one.
Is WebJi an email deliverability consultancy?
No. WebJi® hosts the business mailbox and publishes the SPF, DKIM and DMARC records for domains it serves. It does not run inbox-placement consulting, list cleaning or a bulk-sending network; those jobs are quoted separately or belong with a specialist.
How long does a deliverability fix take to show results?
DNS changes take effect after the TTL expires, so allow at least a day before re-testing. Reputation rebuilds more slowly: warming a new domain or IP typically needs two to four weeks of restrained sending, and blocklist removals depend on each list's re-scan cycle.
