For most businesses, the best bulk email service in 2026 is SendPulse, because its free plan covers 500 subscribers and 15,000 emails a month, paid plans start at $12 a month with unlimited sends, and the same account includes a free SMTP tier, automation and a CRM.
Brevo is the pick if you’d rather pay per email than per contact; Mailchimp for polished templates and integrations; MailerLite for clean, simple newsletters; Constant Contact for small businesses that want phone support; and Twilio SendGrid for developers sending very high volumes through an API.
Sending one newsletter to a few hundred people is easy. Sending tens of thousands of emails and actually landing in the inbox is a different job. Since February 2024, Google has required anyone who sends more than 5,000 messages a day to Gmail addresses to authenticate their domain with SPF, DKIM, and DMARC, offer one-click unsubscribe, and keep reported spam below 0.3%. Yahoo introduced similar rules at the same time.
A good bulk email service handles most of that for you. The hard part is choosing one, because the pricing models differ more than the features do: some charge by contacts, some by emails sent, and some by both. Below are the six mass email services that came up most often in comparisons and reviews, compared on what they cost, what the free plans really include, and how they help with deliverability.

The 6 best bulk email services in 2026
1. SendPulse
SendPulse is a bulk email service with a free plan for 500 subscribers and 15,000 emails a month, paid plans from $12 a month with unlimited emails, and a dedicated IP on its SMTP Pro plan.
SendPulse is an AI-driven email marketing and chatbot platform built for scaling businesses that want to attract leads and turn them into customers. It’s an international company with substantial operations in Brazil and Ukraine, a Meta Partner and an official WhatsApp Business API provider, so the same account can run email campaigns alongside chatbots on WhatsApp, Instagram, Facebook, Telegram, TikTok and Viber. SendPulse is best for small and growing businesses that want generous bulk sending, automation and a CRM without paying for each email.
What it does well
- Drag-and-drop editor with 130+ templates, so a campaign doesn’t need a designer.
- Automation 360: flows triggered by sign-ups, purchases or clicks, which can switch between email and chatbot messages.
- Segmentation and A/B testing on paid plans, with dynamic segments that update as subscribers act.
- Deliverability tools: SPF, DKIM and DMARC domain authentication, an email verifier and a spam checker to clean a list before a big send and protect your sender reputation.
- AI assistant that drafts, translates and adjusts the tone of email copy.
- Built-in CRM that unifies contacts, deals and requests from every channel, plus 40+ integrations.
Pricing: The free plan covers 500 subscribers and 15,000 emails a month. Standard starts at $12 a month for 500 subscribers (or $9.60 billed annually), $78 for 10,000 and $472 for 100,000, all with unlimited emails. Pro adds dynamic segmentation and the email verifier. A pay-as-you-go option and a separate SMTP service are also available: SMTP is free for 12,000 emails a month, and SMTP Pro, at $74.85 a month for 100,000 emails, includes a dedicated IP. See SendPulse official pricing for every tier.
Ratings: 4.6/5 on G2 (720 reviews) and 4.6/5 on Capterra (773 reviews), for the whole platform.
Pros
- Most generous free plan of the six for sending volume

Cons
- A dedicated IP is tied to the SMTP plans
- The Enterprise plan needs at least 2,500 contacts
- Some reviewers find the interface busy
2. Brevo
Brevo is a bulk email service that charges by emails sent rather than contacts: Free allows 300 emails a day for up to 100,000 contacts, and Starter costs $9 a month for 5,000 emails.
Brevo (formerly Sendinblue) flips the usual pricing model. You can store a large contact list cheaply and pay for the volume you actually send, which suits businesses with big lists that email them occasionally. Brevo is best for businesses with large contact lists that send campaigns now and then rather than every week.
What it does well
- Drag-and-drop editor and template library for quick campaign builds.

- AI tools for subject lines, content and send-time optimization.

Standard is $18 a month for 5,000 emails, $35 for 10,000, $75 for 40,000 and $129 for 100,000. Professional starts at $499 a month from 150,000 emails. A dedicated IP is an add-on on Professional and Enterprise at $251 a year. See Brevo official pricing.
Ratings: 4.5/5 on G2 (2,743 reviews) and 4.6/5 on Capterra (3,523 reviews).
Pros
- Cheap way to keep a very large list
- Transactional email on every plan
- Strong automation for the price
Cons
- 300 emails a day on Free is too little for real bulk sends

- Dedicated IP only from Professional ($499/mo)
3. Mailchimp
Mailchimp is an email marketing platform with a free plan for 250 contacts, paid plans from $13 a month for 500 contacts, and 300+ integrations on every plan.
Mailchimp is often the first name people hear, and its strength is the experience: good-looking templates, a mature editor and integrations with almost every e-commerce and CRM tool. The trade-off is cost, which rises quickly as a list grows. Mailchimp is best for brands that value design and integrations and are comfortable paying more as their list grows.
What it does well
- Email builder and templates that look good with little effort.
- Automation flows, up to 200 on Standard and Premium (Essentials is limited to 4 flow steps).
- Segmentation, with predictive segments on Premium.

These are introductory prices for the first 12 months, after which the regular price applies. At 10,000 contacts, Essentials is $110 a month and Standard $135. Sending limits are a multiple of your contacts: 10x on Essentials, 12x on Standard and 15x on Premium. See Mailchimp official pricing.
Ratings: 4.3/5 on G2 (12,989 reviews) and 4.5/5 on Capterra (about 17,600 reviews).

4. MailerLite
MailerLite is an email marketing tool with a free plan for 250 subscribers and 2,500 emails a month, and paid plans from $12 a month for 500 subscribers.
MailerLite keeps things simple, which is exactly why people like it. You get a tidy editor, automation and landing pages without a steep learning curve, and the free plan includes features others charge for. MailerLite is best for creators and small businesses that want simple, good-looking newsletters.
What it does well

- A/B testing on every plan and multivariate testing from Comfort.

Constant Contact has been around for a long time and still shows up in most comparisons of mass email services. Its strength is support and simplicity: live phone help from the cheapest plan, an easy editor and built-in event registration. The trade-off is contact-based pricing that rises quickly as a list grows. Constant Contact is best for small businesses and nonprofits that want hands-on support more than advanced automation.

SendGrid is the most technical service here.

Source: Twilio

Other bulk email services we considered
A few other names come up often when people compare bulk email services. They didn’t make the main list because they’re built for a narrower audience or are usually pricier per contact for plain bulk sending.
- Kit (formerly ConvertKit): built for creators who sell newsletters, courses and digital products.
- HubSpot: email marketing inside a full CRM, best for teams already using HubSpot.
- Klaviyo: e-commerce email and SMS built around store data, popular with Shopify brands.
- Amazon SES, Mailgun and Postmark: developer-focused sending APIs with no marketing editor, often the cheapest per email at very high volume.
SendPulse vs Mailchimp vs Brevo vs Constant Contact vs SendGrid: what a 10,000-contact list costs
For a 10,000-contact list on monthly billing, SendPulse Standard costs $78 with unlimited emails, Brevo Starter $39 for 40,000 emails (about four campaigns a month), MailerLite Comfort $89, Mailchimp Essentials $110, Constant Contact Lite $120 and SendGrid Marketing Campaigns $25 for 30,000 emails. If you send more than about ten campaigns a month (over 100,000 emails), SendPulse’s unlimited sends work out cheaper than paying per email on Brevo.
| Service and plan | Monthly price at 10,000 contacts | Emails included |
| SendPulse Standard | $78 | Unlimited |
| Brevo Starter | $39 (40,000 emails) or $69 (100,000 emails) | Pay per volume |
| Brevo Standard | $75 (40,000 emails) or $129 (100,000 emails) | Pay per volume |
| Mailchimp Essentials | $110 | 100,000 (10x contacts) |
| Mailchimp Standard | $135 | 120,000 (12x contacts) |
| MailerLite Comfort | $89 | 100,000 (10x subscribers) |
| MailerLite Power | $129 | Unlimited (fair use) |
| Constant Contact Lite | $120 | 100,000 (10x contacts) |
| SendGrid Marketing Campaigns | $25 | 30,000 |
At 100,000 subscribers, SendPulse Standard is $472 a month with unlimited emails. For a million emails or more a month, an API service such as SendGrid Pro or Amazon SES is usually the cheapest route.
Bulk email marketing vs. transactional email: which do you need?
Bulk email marketing means newsletters, promotions and announcements sent to a list. Transactional email means one-to-one messages your app triggers, such as receipts and password resets. Marketing tools like SendPulse, Brevo, Mailchimp, MailerLite and Constant Contact focus on the first; SendGrid, Amazon SES, Mailgun and Postmark focus on the second through an API. SendPulse and Brevo cover both in one account, which is handy for small business teams that don’t want two tools.
Deliverability: what Gmail and Yahoo expect from bulk senders
Whichever service you choose, inbox placement depends on a few basics. Authenticate your sending domain with SPF, DKIM and DMARC, add one-click unsubscribe, keep spam complaints under 0.3% (ideally under 0.1%), and remove addresses that bounce. All six services in this list support domain authentication. SendPulse, MailerLite and SendGrid also include list-cleaning tools: SendPulse pairs its email verifier with a spam checker that reviews a campaign before you send it. A dedicated IP only helps once you send consistently at high volume; SendPulse SMTP Pro and SendGrid Email API Pro include one.
Which bulk email service should you choose?
All six platforms are reliable for mass email at small volumes. The differences show up as your mailing list grows past 100,000 subscribers, when the pricing model matters more than any single feature.
Best bulk email service for small business
SendPulse, for the biggest free plan and unlimited sends on paid plans. MailerLite is the simpler alternative, and Constant Contact suits teams that want phone support.
Best for large lists you email occasionally
Brevo, because you pay per email rather than per contact and can store up to 100,000 contacts for free.
Best for high volume (1M+ emails a month)
Twilio SendGrid, with Amazon SES, Mailgun or Postmark as API alternatives. For frequent marketing sends to a large list, SendPulse’s unlimited emails keep costs predictable.
Best for design and integrations
Mailchimp, with 300+ integrations on every plan.
Best for enterprise
SendPulse VIP, Brevo Enterprise, Mailchimp Premium or SendGrid Premier, all with custom pricing.
Conclusion
SendPulse is the strongest all-round choice for bulk email in 2026: its free plan covers 500 subscribers and 15,000 emails a month, paid plans start at $12 with unlimited sends, and SMTP, automation and a CRM come in the same account. Brevo wins for large lists you email occasionally, Mailchimp for design and integrations, MailerLite for simplicity, Constant Contact for phone support, and Twilio SendGrid for developers sending at very high volume.
