2. Mailtrap
G2: 4.8
Capterra: 4.8
Free plan: 4,000 emails/month, 100 contacts
Paid plans: from $15/month
Mailtrap is an email delivery platform for product companies and development teams that send large volumes of email. It handles both transactional and bulk sending from one platform, with a focus on deliverability and analytics.
What makes it good for bulk email?
Mailtrap has a dedicated bulk stream, separate from transactional sending. That separation matters: a bulk campaign generating spam complaints won’t affect the delivery of password resets or account notifications.
Analytics cover opens, clicks, bounces, and spam complaints, broken down by mailbox provider, domain, and sending stream. Email logs are retained for up to 30 days on the Enterprise plan, with shorter windows on lower tiers, giving teams enough history to diagnose deliverability problems before they compound.
For marketers, Mailtrap includes a drag-and-drop email builder, contact management with CSV uploads, and audience segmentation. For developers, it provides a REST API and SMTP service with SDKs for Node.js, Ruby, PHP, Python, Java, and Elixir, plus ready-made code snippets.
Pricing
| Plan | Monthly cost | Emails | Contacts |
| Free | $0 | 4,000 | 100 |
| Basic | From $15 | 10,000+ | Up to 5,000 |
| Business | From $85 | 100,000+ | Up to 100,000 |
| Enterprise | From $750 | 1,500,000+ | Up to 1,500,000 |
Pros
- Separate sending streams for bulk and transactional email
- Per-provider deliverability analytics
- Dedicated IP with automatic warmup on Business plan and above
- ISO 27001 and SOC 2 certified, GDPR compliant
- 24/7 support on Business and Enterprise plans
Cons
- Free and Basic plans have email support Monday-Friday only; 24/7 support requires Business plan or above
- Native integrations are still growing; many connections go through Zapier or Make
3. Maileroo
G2: 4.8
Capterra: 5.0
Free plan: 3000 emails/month
Paid plans: from $10/month (25,000 emails)
Maileroo combines bulk campaigns with transactional sending through a single SMTP relay and API. It targets startups and small-to-mid teams that want both in one place without enterprise-level complexity.
What makes it good for bulk email?
Maileroo covers SPF, DKIM, and DMARC authentication and tracks opens, clicks, bounces, and unsubscribes. Templates, list management, segmentation, and analytics share the same dashboard as transactional sending. Dedicated IPs are included on higher tiers (250,000+ emails/month) at no extra cost.
Pricing is volume-based and scales without feature gating. The trade-off is that granular role-based permissions, complex multi-account structures, and highly customized setups are outside what Maileroo handles well – for those requirements, SendGrid or Amazon SES is a better fit.
Pricing
| Plan | Monthly cost | Emails | Notes |
| Free | $0 | 3,000 | Core sending features |
| Starter | From $10 | 25,000 | Scales to higher volumes |
| Higher tiers | Custom | 250,000+ | Dedicated IP included |

- Bulk and transactional email from one platform
- Volume-based pricing without feature gating
- SPF, DKIM, and DMARC out of the box

Sender is an email and SMS marketing platform designed for small teams. The free plan covers 15,000 emails per month to 2,500 subscribers, with automation workflows, segmentation, analytics, and 24/7 support – most platforms restrict support to paid users.
What makes it good for bulk email?
The drag-and-drop editor produces responsive templates. Setting up a campaign follows a short path: pick a template, customize it, select your audience, and send. Automation uses trigger-action logic that’s approachable for teams without email operations experience.
Paid plans add SMS campaigns alongside email.

Beyond email, Omnisend supports SMS, web push notifications, and connects with Google Customer Match and Facebook Custom Audiences. All features are available on the free plan; the only limits are send volume and contact count.

Brevo (formerly Sendinblue) is a multi-channel marketing platform covering email, SMS, WhatsApp, push notifications, and a built-in CRM.
What makes it good for bulk email?
The automation builder works on a visual canvas – you map workflows using triggers, conditions, and actions. Welcome sequences, re-engagement flows, and cart reminders are all configurable without code.
The “Send at best time” feature analyzes each contact’s engagement history and delivers the email when they’re most likely to open it, rather than at a fixed time you set manually.
Brevo includes 40+ newsletter templates and an AI assistant for generating or refining email content.
Pricing
| Plan | Monthly cost | Emails |
| Free | $0 | 300/day |
| Starter | $9 | From 5,000/month |

The real-time email validation API embeds directly into sign-up forms, stopping invalid addresses before they enter your list. Bulk list validation from the dashboard is also available – useful before a large send.
A/B testing covers up to 10 email versions at once, tracking opens, clicks, and engagement across variations in subject line, sender name, and content. This feature requires the Premium plan.
The automation builder uses draggable action blocks. It covers follow-ups, drip campaigns, and trigger-based sends, but won’t handle complex multi-step workflows.
Multi-user real-time collaboration is built in, which is useful for small marketing teams working on campaigns at the same time.
Pricing

Wrapping up: How to choose a bulk email service
Four factors determine whether a provider fits your needs.
Deliverability. Inbox placement depends on whether your provider enforces SPF, DKIM, and DMARC and protects your IP reputation. If you send both marketing and transactional emails, separate streams keep a campaign complaint spike from affecting critical messages. Mailtrap handles this natively; Mailjet does not.
Ease of use. A drag-and-drop builder and clear documentation matter when your team doesn’t have dedicated email developers. Selzy, Brevo, and Sender have the lowest barrier to entry.
Pricing model. Some services charge by emails sent, others by contact count. Omnisend’s contact-based pricing rises quickly as your list grows. Mailtrap and Mailjet charge by email volume. Check overage rates before committing to any plan.
Separate sending streams. This is the one technical detail that affects everyone who sends both campaigns and transactional emails. A campaign that generates complaints should not delay password resets or order confirmations. Mailtrap enforces stream separation natively; most others require workarounds or don’t offer it at all.
The right choice by situation:
- Choose Selzy for an accessible builder, strong authentication features, and a low entry price.
- Choose Mailtrap when per-provider deliverability analytics and separate sending streams are the priority.
- Choose Maileroo for bulk and transactional email on a single affordable platform without enterprise complexity.
- Choose Sender to keep costs low – the free plan includes 15,000 emails/month with 24/7 support.
- Choose Omnisend for ecommerce: Shopify integration and pre-built automation flows cover the most common store scenarios.
- Choose Brevo when email, SMS, and WhatsApp campaigns need to run from one platform.
- Choose Mailjet for built-in email validation and multi-user collaboration without needing additional tools.
Every provider on this list offers a free plan. Running a real campaign through one or two before committing gives you actual inbox placement data under your sending conditions – which is more reliable than any feature comparison.
