Business email on own domain: two records that help win tenders

A free webmail address makes a bid look like one person, not a firm, and some buyers screen it out. Move to an address on your own domain and set two DNS records, MX and SPF, so mail arrives and stays out of spam folders.

Why business email on own domain matters in a tender

A tender file is read by a person with a stack of other files on the desk. The contact line on your cover letter is one of the first things they see. An address on a free webmail service says one person set it up on a phone. An address like accounts@yourfirm.in says a firm stands behind the bid.

That is the plain case for business email on own domain. Some purchase teams list a company address as a condition in the bid form. Others do not say it, but their mail filters trust free addresses less. Your reply to a query then lands in a folder nobody opens until the closing date has passed. One lost clarification can cost you the whole tender.

There is a second cost. When a sales person leaves, a free address leaves with them. Every buyer who wrote to that address now writes into a box you cannot open. With your own domain, you keep the mailbox, reset the password and hand it to the next person on the same day.

What you need before you start

You need three things. A domain name you already own, such as yourfirm.in. A mail service that will hold the mailboxes. And the login for the panel where your domain's DNS records live, which is usually the company you bought the domain from or your hosting account.

If you do not have a mail service yet, the business hosting plan runs your website and your mailboxes on the same account, so the records below point to one place. Set aside about 30 minutes for the work and a day for the changes to spread.

Before you touch anything, take a screenshot of the DNS panel as it stands. If a step goes wrong, you can put every line back as it was.

Record one: MX, where your mail lands

The MX record tells the rest of the internet which server takes in mail for your domain. Without it, a buyer's reply to accounts@yourfirm.in bounces back to them with an error, and most buyers will not try twice.

In the DNS panel, add a record with these fields. Type: MX. Host or name: @, which means the bare domain. Value: the mail server name your mail service gives you, for example mail.yourfirm.in. Priority: 10. TTL: 3600, which is one hour.

If your mail service gives you two server names, add two MX records. Give the main one priority 10 and the backup priority 20. Lower numbers are tried first.

Then look for any old MX records left from a past setup and delete them. Two sets of MX records pointing at two different services is the most common reason mail goes missing after a move.

Record two: SPF, who may send for you

The MX record handles mail coming in. The SPF record handles mail going out. It is a line of text that lists the servers allowed to send mail in your domain's name. A buyer's mail system reads it when your quote arrives. If the sending server is on the list, the mail passes this check. If it is not, the mail is far more likely to be marked as spam.

Add a record like this. Type: TXT. Host or name: @. Value: v=spf1 a mx ~all. TTL: 3600.

Read left to right, that says: this is an SPF record; the server behind the website may send; the servers in the MX record may send; treat everything else with suspicion. If your mail service gives you its own include line, use the exact text it gives you in place of the example.

Keep one SPF record per domain. If you find an old TXT line that also starts with v=spf1, merge the two into one line. Two SPF lines make the check fail for every mail you send, which is worse than having none.

After a week of clean sending, you can change ~all to -all. That tells receiving servers to refuse mail from any server not on your list, which stops others from sending fake quotes in your name.

How to test it in ten minutes

DNS changes often show within an hour. Allow up to 48 hours before you decide something is wrong.

First, send a mail from your personal address to your new business address. If it arrives, the MX record works.

Second, send a reply from the business address back to the personal one. Open the message and use the option to show the original message or its full headers. Search the text for spf=pass. If you see it, the SPF record works. If you see spf=fail or softfail, check the record for spelling mistakes and make sure only one SPF line exists.

Third, send one test to a contact at a larger company, and ask whether it landed in the main inbox or in spam. Their filters are often stricter than a free inbox, and they behave more like a buyer's would.

The mailboxes to make first

Start small. Most small firms need four kinds of box on day one: one for each owner by name, accounts@ for invoices and payment queries, sales@ for quotes and tenders, and info@ for the website form.

Shared boxes like sales@ matter most in tenders. Put sales@ as the tender contact, not a person's name, and give two people access. If one person is on leave in the last week before a deadline, the other still sees the buyer's question and can answer it the same day.

Add a plain signature to every box: full name, role, company name, phone number and the website address. Leave out large images. A signature of five short lines loads on every phone and does not trip spam filters.

The next two records, when you are ready

MX and SPF are the two that matter on day one. Two more records make your mail harder to fake. DKIM adds a signature to each mail that shows it was not changed on the way. DMARC tells receiving servers what to do when a mail fails the other checks, and sends you a daily report. Your mail service gives you the DKIM text to paste in. A DMARC record can start as v=DMARC1; p=none, which only watches and blocks nothing. You can tighten it after a month of reports.

What it takes in time

For a firm with one domain and four mailboxes, the full setup is about an hour of work: 30 minutes for the two records, 20 for the mailboxes and signatures, and 10 for the tests. Moving old mail from free addresses into the new boxes takes longer, roughly 15 minutes per mailbox, and can wait for a quiet evening.

If you would rather hand the job over, we set the records, create the boxes and run the tests, and you get the logins once every check passes.
