How to Send Bulk Emails from Hostinger (2026 Guide)

Your website runs on Hostinger, your professional email address does too, and now you want to write to 200 customers about a new offer, with each email mentioning their name. The issue? Hostinger Mail, Hostinger’s webmail, has no mail merge, so everyone would get the exact same message. And BCC won’t take you far, since Hostinger caps every email at 100 recipients.

The fix is to connect your Hostinger mailbox to Mailmeteor, a mail merge tool with 7 million users and a 4.9/5 rating from 10,000+ reviews, through SMTP, the standard protocol for sending email. Each contact then receives their own personalized email, sent from your Hostinger address.

In this guide, you’ll find the Hostinger SMTP settings, the sending limits for each Hostinger email plan, and a step-by-step setup to send your first email campaign.

Why Send Bulk Emails From Hostinger?

If your website and domain live at Hostinger, your business address is probably the one your customers already recognize. What Hostinger Mail doesn’t give you is a way to reach all of them at once, personally.

Here’s what connecting it to Mailmeteor changes ⤵️

Send From Your Business Domain

Your emails go out from an address like [email protected], not from a generic one. They’re sent through Hostinger’s servers, so they carry the SPF and DKIM records configured for your domain. Replies come back to the mailbox you already read in Hostinger Mail or your usual email app.

Get What Hostinger Mail Can’t Do

Hostinger Mail is a solid inbox, but it sends one message at a time, identical for everyone. Once connected to Mailmeteor, your mailbox can:

• Address every customer by name, and mention their plan, city, or last purchase.
• Load recipients from a Google Sheet or a CSV export of your customer list.
• Verify addresses before sending, so you don’t spend your daily quota on addresses that don’t exist.
• Include an unsubscribe link, and automatically stop emailing people who opt out.
• Track who opens, clicks, and replies.
• Schedule follow-ups automatically to people who haven’t answered.

Know Where the Limits Are

Hostinger caps each mailbox at a set number of emails per day, from 100 on free and trial mailboxes to 3,000 on Business Standard and Premium. That’s plenty for customer updates, event invitations, or prospecting, but not for a weekly newsletter to your whole customer base. For that, Hostinger sells a separate email marketing product, and dedicated newsletter platforms are built for the job too.

What You Need to Send Bulk Emails From Hostinger

To send bulk emails from Hostinger with Mailmeteor, you need:

• An email address hosted by Hostinger, like [email protected]. Any Hostinger Email plan works, including the free trial that comes with some hosting plans.
• The mailbox password, or an app password created for Mailmeteor. This isn’t the password you use to log in to Hostinger.
• A Mailmeteor Premium plan or higher, which you need to connect a custom sender like your business address.

How to Get Your Hostinger Mailbox Credentials

Mailmeteor signs in to your mailbox with your full address and either the mailbox password or an app password. Hostinger keeps these separate from your account login, and mixing them up is the most common reason a connection fails.

Option 1: Create an App Password (Recommended)

An app password is a separate code that gives one app access to your mailbox. You can revoke it without touching your main password. Hostinger notes that not every email plan supports app passwords, so if you don’t see the option, use Option 2.

1. In the Hostinger dashboard, go to Emails.
2. Select the domain of your mailbox, then click Mailboxes.
3. Open the options menu (⋮) next to your mailbox and select App passwords.
4. Click Generate, name the password “Mailmeteor”, then click Generate again.
5. Click Copy. Hostinger only shows the password once, so paste it somewhere safe until you’ve finished the setup.

Option 2: Use Your Mailbox Password

If you’d rather use the mailbox password and don’t remember it, reset it from the same menu:

1. In Emails, click Mailboxes next to your domain.
2. Open the options menu (⋮) next to your mailbox and select Change Password.
3. Enter a new password and click Update.

Remember to update the password in any other email app that uses this mailbox, such as your phone.

How to Send Bulk Emails From Hostinger With Mailmeteor

With your credentials ready, the rest happens in Mailmeteor and takes about 5 minutes. You’ll register your Hostinger address once, then reuse it for every campaign.

Step 1: Register Your Hostinger Address in Mailmeteor

1. Log in to your Mailmeteor Dashboard.
2. From Products, open More and select Senders.
3. Select Add sender.
4. Fill in the display name recipients should see, then your Hostinger email address.
5. Hit Save.

Step 2: Enter Hostinger’s SMTP Server

1. Under Email services, press the + button.
2. Pick Configure mail server.
3. In the Sending server block, enter smtp.hostinger.com in the Server name field.
4. Fill in Username with your full Hostinger address, such as [email protected].
5. In Password, enter your app password or your mailbox password.

Mailmeteor fills in the port and encryption for you automatically, so there’s nothing else to adjust on the sending side.

Step 3: Enter Hostinger’s IMAP Server

IMAP is optional for sending, but without it Mailmeteor can’t see replies arriving in your Hostinger inbox, and follow-ups could reach customers who already responded. Here’s how to configure it ⤵️

1. In the Reception server block, enter imap.hostinger.com as the Server name.
2. Reuse your full Hostinger address as the Username.
3. Enter the same password.
4. Select Save, then Done.

And voilà. Mailmeteor automatically fills in 993, the port Hostinger uses for IMAP. Your Hostinger mailbox is now connected to Mailmeteor.

Step 4: Create Your Hostinger Campaign

1. Click New campaign in the Dashboard.
2. In the From field, open the dropdown (▼) and select your Hostinger address.
3. Click Select recipientss. Then connect a Google Sheet, upload a CSV file, choose a saved list, or paste emails to add recipients.
4. Write the subject line and body of your email.
5. Personalize with variables like {{ firstname }} or {{ company }}, matching the column names in your list.
6. Open Preview to review a few emails as your recipients will see them.

The best part? Each contact receives a separate email, so Hostinger’s cap of 100 recipients per message doesn’t apply. Every email still counts toward your mailbox’s daily limit, though.

Prefer to stay in your spreadsheet? Mailmeteor for Google Sheets can send the same campaign from your Hostinger address, straight from the sheet that holds your customer list.

Step 5: Match Autopilot to Your Daily Limit

Every email your campaign sends counts toward your mailbox’s daily limit. Autopilot helps you stay under it by releasing your emails gradually, over as many hours or days as you need.

1. Click Autopilot in your campaign.
2. Set the days and hours when emails can go out.
3. Pick the delay between emails. One minute is the minimum.
4. Set a daily cap below your plan’s limit. Under 100 on a free or trial mailbox, and a few hundred at most on Business Starter until your mailbox has a sending history.
5. Click Apply.

The interval sets the speed, and your daily cap is what keeps you inside Hostinger’s limit. Set the cap below your plan’s allowance. For example, 80 a day on a mailbox limited to 100. Leave some room for emails you send by hand from the same mailbox, since they count too. Autopilot always tells you how long the campaign will take.

Step 6: Send a Test, Then Go

1. Send yourself a test email.
2. Look it over in your inbox and check the layout, links, and variables.
3. Hit Send emails to start the campaign.

All done. Your campaign now goes out from your Hostinger address at the pace you set, and the Dashboard tracks opens, clicks, and replies as they arrive.

Hostinger SMTP and IMAP Settings

Mailmeteor talks to two Hostinger servers. One to send your emails (SMTP) and one to read replies and bounces (IMAP).

Here’s the full configuration for Hostinger Email ⤵️

Mailmeteor handles the encryption automatically. For reference, Hostinger uses SSL on port 465 and STARTTLS on port 587. These settings are also in your Hostinger dashboard. Go to Emails > Mailboxes > Connect apps & devices, then open Advanced settings. Hostinger only shows port 465 there, but 587 works too.

Keep three points in mind:

• Your mailbox password isn’t your Hostinger account password. The account password logs you in to the Hostinger dashboard and won’t work here.
• Titan Email uses different servers: smtp.titan.email (port 465) and imap.titan.email (port 993).
• Change the port only if you need to. If the connection fails on 465, open Advanced options in Mailmeteor, switch to 587, and leave Security on Auto.

Hostinger Email Sending Limits by Plan

Hostinger publishes its email limits, and they apply to each mailbox over a rolling 24-hour period. Sending and receiving are counted separately, so incoming emails don’t eat into your sending quota.

Each mailbox gets its own allowance, so a second address on the same domain doesn’t share the first one’s quota. Because the window is rolling, capacity comes back gradually as your oldest sends pass the 24-hour mark.

To see the limits for your mailbox, open Emails in the Hostinger dashboard, click Mailboxes next to your domain, then click View limits. Mailmeteor’s own plan limits apply too, and whichever is lower sets your pace.

How to Keep Your Hostinger Emails Out of Spam

Staying under your quota keeps your mailbox working. Reaching the inbox also depends on your domain’s authentication, your list, and your content ⤵️

Check Your Domain’s SPF, DKIM, and DMARC Records

SPF, DKIM, and DMARC are DNS records that help email providers check that your emails really come from your domain. Without them, your emails are more likely to land in spam. Where you add them depends on where your domain’s DNS is managed:

• At Hostinger: go to Emails > Mailboxes > Domain settings and click Connect automatically. Hostinger adds the records for you. No button? Your DNS is managed elsewhere.
• Somewhere else (Cloudflare, GoDaddy, Namecheap, etc.): add the records below at that provider.

Verify Your Contact List

Invalid addresses bounce, which hurts your sender reputation. And on Hostinger every bounced email still uses part of your daily quota. To avoid bounces, run your list through our free Email Checker, or turn on Mailmeteor’s email verification to skip invalid addresses automatically.

Write Emails That Get Past Spam Filters

Spam filters are more suspicious of emails that look mass-produced. To keep your campaign looking personal:

• Personalize more than the greeting. A detail about the customer’s plan or last order makes each email genuinely different.
• Steer clear of spam words like “free”, “guaranteed”, or “act now”, especially in your subject line.
• Keep the layout simple. A few short paragraphs, one or two links, and little or no images.
• Add an unsubscribe link to promotional and prospecting emails, so uninterested contacts can leave without flagging you as spam.

Before sending, test your copy with our free Spam Checker. For a deeper check, Mail-Tester gives you a one-time email address. Send your test email there, and it reports any authentication or content problems it finds.

Build Volume Over Time

A mailbox that has only ever sent a few emails a day, or a brand-new domain, needs time to earn trust with inbox providers. Start well below your daily limit, check bounces and replies after each send, and increase volume gradually. To build that reputation before a big campaign, you can also use Mailmeteor’s email warm-up.

How to Fix Hostinger SMTP Connection Errors

Most Hostinger connection problems come from a password mix-up or a used-up daily quota. Here’s how to sort them out ⤵️
