Why You Need SMTP for WordPress
WordPress's default email system has problems:
- Emails go to spam folders
- Contact forms don't work reliably
- WooCommerce order emails never arrive
- Password reset emails fail to send
The Solution: Rapid Host BD's SMTP service ensures your emails are delivered to the inbox every time.
Prerequisites
Before you start, make sure you have:
✓ Active Rapid Host BD SMTP Account - Purchase from https://rapidhostbd.com/cheap-smtp-email-hosting/ (plans start at ৳49/month)
✓ SMTP Credentials Email - You received this after purchasing. It contains:
- SMTP server address
- Port number
- Username
- Password
✓ WordPress Admin Access - You need to log in to install plugins
✓ DNS Access - Either through Cloudflare, cPanel, or your domain registrar
Don't have your credentials? Contact Rapid Host BD support: +8801988366305
Step 1: Set Up SPF Record (5 minutes)
SPF tells email providers you're authorized to send emails from your domain. Without it, emails go to spam.
Using Cloudflare:
- Log in to Cloudflare → Select your domain
- Click DNS → Click Add record
- Fill in:
- Type: TXT
- Name: @
- Content:
v=spf1 include:_spf.rapidhostbd.com ~all - TTL: Auto
- Click Save
Using cPanel:
- Log in to cPanel → Find Zone Editor
- Select your domain → Click Add Record
- Fill in:
- Type: TXT
- Name: yourdomain.com
- Record:
v=spf1 include:_spf.rapidhostbd.com ~all
- Click Add Record
⚠️ Important: Only have ONE SPF record. If you already have one, modify it by adding include:_spf.rapidhostbd.com before the ~all part.
Wait 15-30 minutes for DNS changes to take effect.
Step 2: Install WP Mail SMTP Plugin (3 minutes)
- Log in to your WordPress dashboard
- Go to Plugins → Add New
- Search for "WP Mail SMTP"
- Click Install Now on "WP Mail SMTP by WPForms"
- Click Activate
Step 3: Configure SMTP Settings (5 minutes)
After activation, go to WP Mail SMTP → Settings
General Settings:
From Email: info@yourdomain.com (use your domain, not Gmail)
From Name: Your Company Name
✓ Check Force From Email
✓ Check Force From Name
SMTP Settings:
- Select Other SMTP as mailer
- Enter your Rapid Host BD details:
SMTP Host: Your server address (from credentials email)
Encryption: Select TLS
SMTP Port: 587
Auto TLS: ON
Authentication: ON
SMTP Username: Your username (from credentials email)
SMTP Password: Your password (from credentials email)
- Click Save Settings
Example Configuration:
From Email: info@yourstore.com
From Name: YourStore
Mailer: Other SMTP
SMTP Host: smtp.rapidhostbd.com
Encryption: TLS
SMTP Port: 587
SMTP Username: smtp@yourstore.com
SMTP Password: [your password]
Step 4: Test Email Delivery (2 minutes)
- Go to WP Mail SMTP → Email Test
- Enter your personal email in Send To
- Click Send Email
Check your inbox (and spam folder) - the test email should arrive within 1-2 minutes.
Test Your Score:
- Visit https://www.mail-tester.com
- Copy the email address shown
- Send a test email to that address
- Click "Then check your score"
Aim for 8/10 or higher - this means good deliverability.
Step 5: Set Up DKIM (Optional - 3 minutes)
DKIM adds extra security and improves deliverability.
- Contact Rapid Host BD support (WhatsApp: +8801988366305)
- Ask for your DKIM record
- Add it to your DNS the same way you added SPF (as a TXT record)
Or log in to your Rapid Host BD client area and find DKIM settings under your SMTP service.
Step 6: Add DMARC Record (Optional - 2 minutes)
DMARC provides additional email authentication.
Add this TXT record to your DNS:
Name: _dmarc
Content: v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com
Replace yourdomain.com with your actual domain.
Common Issues & Quick Fixes
❌ "Could not authenticate" Error
Fix: Double-check username and password. Copy-paste from your credentials email to avoid typos.
❌ "SMTP connect() failed" Error
Fix: Try port 465 instead of 587, and change encryption to SSL.
❌ Emails Going to Spam
Fix:
- Verify SPF record is set correctly
- Set up DKIM (contact Rapid Host BD support)
- Check your mail-tester.com score
❌ Test Email Works But Forms Don't
Fix: Check your contact form plugin settings - make sure the sender email uses your domain.
