Pros & Cons
Brevo
Pros
- The free plan sends 300 emails a day and allows up to 100,000 contacts, which is generous for testing the product or for very small lists.
- Pricing is based mainly on how many emails you send, so businesses with large lists that email rarely can keep costs low.
- Transactional email through an API and SMTP, outbound webhooks and a Zapier connector are included on every plan, including Free.
- Email, SMS, WhatsApp, push, live chat and a sales CRM are available from one vendor.
Cons
- On Starter and Standard, the lowest send tiers cap contacts at 500 to 2,500, which can force earlier upgrades.
- Pop-ups, contact scoring, WhatsApp, inbound webhooks and phone support all require Professional, which starts at $499 a month.
- Many reviewers on Capterra and Trustpilot report sudden account suspensions with unclear reasons and slow reinstatement.
- SMS and WhatsApp are billed as prepaid credits on top of the plan price, and the CRM is a separate purchase.
MMailrelay
Pros
- The free plan allows 80,000 emails a month to 20,000 contacts with open and click tracking, which is far more than most competitors' free tiers.
- A/B testing, segmentation, landing pages, automation and abandoned-cart flows are included even on the free plan.
- Official free WordPress and WooCommerce plugins sync customers, products and carts.
- Data is stored in the EU, and Mailrelay acts as a GDPR Article 28 processor on all accounts.
- SPF, DKIM and DMARC setup and custom tracking domains are available on the free account.
Cons
- There is no native Shopify integration and no official Zapier app; the vendor points users to Make or the API instead.
- The Standard paid plan does not include open and click tracking.
- Monthly plans require a 12-month commitment.
- Reviewers describe the automation as limited compared with larger rivals, and some report bugs and poor support experiences.
- G2 shows an average of only 3.2 out of 5 from a small number of reviews.
