If you run a website, you already know — email isn’t optional anymore.
It’s one of the most powerful tools for communication, customer support, and marketing. But not all mailing services are created equal.
From sending order confirmations and newsletters to handling contact forms or automations, choosing the right mailing service can make a world of difference in how your business grows online.
In this guide, we’ll break down exactly how to choose the perfect mailing service for your website — step by step — so your emails always reach inboxes, not spam folders.
💡 What Is a Mailing Service and Why Do You Need It?
A mailing service (also called an email delivery or email marketing platform) helps your website send and manage emails reliably.
Depending on your website’s purpose, this could include:
- Sending transactional emails — order receipts, password resets, contact form responses.
- Managing marketing emails — newsletters, promotions, announcements.
- Automating customer journeys — onboarding, follow-ups, abandoned cart reminders.
Using your web host’s default mail server may sound convenient — but it’s risky. Shared hosting servers are often blacklisted or rate-limited, meaning your emails can easily end up in spam.
That’s where a professional mailing service comes in.
🚀 Step 1: Identify What Type of Emails You’ll Send
Before choosing any service, you need to understand your email goals.
Most websites send two types of emails — transactional and marketing — and each requires a different approach.
🧾 1. Transactional Emails
These are one-to-one messages triggered by user actions.
- Order confirmations
- Password resets
- Account activations
- Contact form replies
Best services for transactional emails:
- Amazon SES
- Mailgun
- SendGrid
- Brevo (formerly Sendinblue)
These platforms are built for reliability, speed, and deliverability.
📣 2. Marketing Emails
These are bulk or campaign-based messages you send to a subscriber list.
- Newsletters
- Product updates
- Sales promotions
- Blog announcements
Best services for marketing emails:
- Mailchimp
- Brevo
- ConvertKit
- ActiveCampaign
- Moosend
Marketing platforms focus on design, automation, and audience segmentation.
👉 Pro tip:
Many businesses use both types: one transactional service for site-triggered emails and one marketing platform for newsletters.
⚙️ Step 2: Check Deliverability Rates
Deliverability means your emails actually land in someone’s inbox — not the spam folder.
This is the most crucial factor when choosing a mailing service. Even beautiful templates and smart automations won’t help if your emails never arrive.
🔍 What to check:
- Sender reputation management: Does the service monitor IP and domain reputation?
- Dedicated IP option: Essential for large senders to control deliverability.
- SPF, DKIM, and DMARC support: These authentication records prevent spoofing and build trust.
- Blacklist monitoring: The service should automatically detect and fix blacklisted IPs.
Top-rated for deliverability:
- SendGrid
- Amazon SES
- Brevo
- Mailgun
Test before committing — send a few emails to multiple inbox types (Gmail, Outlook, Yahoo) and see if they arrive correctly.
💌 Step 3: Evaluate Ease of Integration With Your Website
Your mailing service should integrate easily with your CMS, e-commerce platform, or CRM.
Popular integrations to look for:
- WordPress plugins: WP Mail SMTP, MailPoet, MailerLite, Sendinblue, etc.
- E-commerce tools: WooCommerce, Shopify, Magento integration.
- Form builders: Contact Form 7, Gravity Forms, or Elementor Form.
- API or SMTP support: For developers who need custom setups.
If you’re using WordPress, services like Brevo, Mailchimp, or MailerLite offer direct plugins — no coding required.
Pro tip:
If you use contact forms or WooCommerce, install a mail delivery plugin like WP Mail SMTP to route all outgoing emails through your chosen service.
🧠 Step 4: Check Automation and Personalization Features
Modern mailing services go far beyond just sending emails — they help you create smarter, more personal communication.
🔁 Key features to look for:
- Autoresponders: Automatically welcome new subscribers or confirm form submissions.
- Segmentation: Target users based on behavior (like clicks or purchases).
- Dynamic content: Personalize subject lines and messages using variables (e.g., first name).
- Behavioral triggers: Send emails based on user actions, like cart abandonment or page visits.
Platforms that excel here:
- ActiveCampaign (advanced automation)
- ConvertKit (creator-focused automation)
- Brevo (affordable yet powerful workflows)
If automation matters to your business — such as drip campaigns or lead nurturing — make sure your mailing service offers visual workflows and logic-based triggers.
💼 Step 5: Compare Pricing and Scalability
Every email provider has its own pricing structure — usually based on number of subscribers or emails sent per month.
📊 Pricing models:
| Type | Description | Example Services |
|---|---|---|
| Subscriber-based | Pay per number of contacts in your list | Mailchimp, ConvertKit |
| Volume-based | Pay per number of emails sent monthly | Mailgun, Amazon SES |
| Hybrid | Combines both | Brevo, Moosend |
Pro tip:
If you send fewer than 10,000 emails/month, Brevo and MailerLite are budget-friendly.
If you’re sending 100K+ emails, consider Amazon SES for unbeatable pricing.
Also, look for free plans to test the platform before paying:
- Brevo – 300 emails/day (free plan)
- Mailchimp – 500 contacts (free tier)
- MailerLite – 1,000 subscribers (free)
- Amazon SES – free for first 62,000 emails if hosted on AWS
🔒 Step 6: Prioritize Security and Compliance
Email security isn’t just about avoiding spam — it’s about protecting user data.
Make sure your mailing service complies with global privacy laws like:
- GDPR (Europe)
- CAN-SPAM (USA)
- CASL (Canada)
✅ Security must-haves:
- Two-factor authentication (2FA)
- Encrypted data storage
- Custom DKIM/SPF authentication
- Dedicated IP addresses (optional but valuable)
Some platforms like Brevo and Mailchimp even provide GDPR-friendly tools such as double opt-in and consent tracking — essential for EU-based audiences.
💬 Step 7: Review Template Design and Editor Options
An email is your brand’s digital handshake — so looks matter.
Modern mailing services come with drag-and-drop builders and ready-made templates that make designing professional emails easy, even without coding.
🖌️ Look for:
- Mobile-responsive templates
- Drag-and-drop builder
- HTML editor for custom layouts
- Reusable templates and saved blocks
- Brand color customization
Best for design flexibility:
- Mailchimp (hundreds of templates)
- Moosend (intuitive visual editor)
- Brevo (simple but powerful)
- BeeFree (great for external template building)
Remember — a clean, well-structured email layout not only improves conversions but also avoids spam filters.
📈 Step 8: Analyze Reporting and Analytics Tools
You can’t improve what you don’t measure.
An ideal mailing service gives you deep insights into how your audience interacts with your emails.
📊 Look for analytics on:
- Open rate and click rate
- Bounce rate and unsubscribes
- Link heatmaps
- Conversion tracking
- A/B testing (subject lines, send times, design)
Services like ActiveCampaign and Brevo include visual dashboards showing engagement over time, making it easier to refine your strategy.
🌍 Step 9: Consider Global Reach and Time Zone Support
If your audience spans multiple countries, look for services that support localized sending, multi-language templates, and time zone scheduling.
Some advanced platforms even optimize send times using AI — sending each email when a specific user is most likely to open it.
🌐 Recommended tools for global campaigns:
- Mailchimp (AI-based send time optimization)
- Brevo (time zone auto-detection)
- Campaign Monitor (localized content)
This ensures your emails hit inboxes at the right time — even if your subscribers live across the world.
🧩 Step 10: Check Customer Support and Reliability
When your business relies on email, you can’t afford downtime.
Choose a provider known for 24/7 support, fast response times, and extensive documentation.
🕐 Questions to ask:
- Is live chat or phone support available?
- Are response times quick (especially during outages)?
- Does it have a resource library or community forum?
Top-rated for support:
- Brevo (24/7 chat and ticket support)
- ActiveCampaign (dedicated success managers for premium plans)
- MailerLite (great community and tutorials)
💬 Step 11: Think Long-Term — Scalability and Growth
A mailing service isn’t just for sending newsletters. As your business grows, you might need advanced tools like:
- CRM integration (HubSpot, Zoho, Pipedrive)
- Advanced segmentation
- Sales automation
- Multi-channel messaging (SMS, WhatsApp, chatbots)
Pro tip:
Choose a platform that can grow with you.
Brevo and ActiveCampaign, for instance, start simple but scale to enterprise-level automation without forcing a platform switch later.
🧠 Step 12: Test Before Committing
Most mailing services offer free plans or trials — use them!
You’ll get hands-on experience with their interface, support quality, and deliverability.
Checklist for testing:
- Send test emails to multiple inbox types.
- Check design rendering on mobile vs desktop.
- Measure delivery time and inbox placement.
- Test automation triggers and segmentation.
- Evaluate reporting accuracy.
Once you find a service that checks all the boxes, upgrade to a paid plan for better deliverability and features.
