Brevo — formerly known as Sendinblue before its 2023 rebrand — has grown significantly in popularity as a Mailchimp alternative, particularly among budget-conscious organizations. Its generous free tier (300 emails per day) and competitive transactional email pricing have attracted many users. Some Jewish organizations and Charedi businesses have also adopted it. Here’s what you need to know if you’re considering Brevo for a frum-community audience.

What Brevo Does Well

Brevo has invested heavily in building a competitive feature set:

Strong free tier — up to 300 emails/day at no cost, unlimited contacts
SMS marketing in addition to email — useful for combining channels
Marketing automation with visual workflow builder
Transactional email capability (order confirmations, receipts) on the same platform
European Union data residency options (relevant for Israeli organizations under GDPR considerations)
Competitive pricing compared to Mailchimp and Constant Contact at scale

Brevo’s Limitations for the Frum Community

No File Attachment Support

Brevo does not support email file attachments through its marketing email product. Like other major platforms, it requires files to be hosted externally with links in the email body. For transactional emails (automated individual sends), Brevo’s API does support attachments — but this requires technical development and is not accessible through the standard marketing interface.

For a shul administrator, school secretary, or mosad administrator who needs to attach a PDF schedule, Hebrew invitation, or organizational document to an email campaign — Brevo’s standard product does not support this. KosherEmail supports direct attachments without any technical setup required.

Kosher Filter Infrastructure

Brevo’s email infrastructure was designed for European and North American mainstream commercial audiences. Its sending domains, image CDNs, and link-tracking infrastructure are not vetted for kosher internet filter compatibility. Emails sent to filtered recipients — using NetFree, Rimon, or similar services — may arrive with missing images or broken links.

This is not a Brevo-specific problem; it affects all mainstream email platforms. But it’s worth noting that Brevo has no documented awareness of or solution for the kosher filter compatibility issue.

European Focus Doesn’t Help Israeli Charedi Users

Brevo’s European infrastructure might seem like an advantage for Israeli users, but data residency in the EU doesn’t affect filter compatibility. Charedi users in Israel using NetFree — which routes through Israeli ISPs and DNS filtering — face the same filter compatibility issues with Brevo that they face with American platforms.

Automation Without Jewish Calendar Awareness

Brevo’s visual automation builder is genuinely powerful, but it has no knowledge of the Jewish calendar. A welcome sequence or fundraising automation running for a few weeks will inevitably schedule sends on Shabbos or Yom Tov unless manually audited. For an organization serving the Orthodox community, this requires ongoing manual oversight that is easy to miss.

Who Switched from Brevo to KosherEmail and Why

We’ve worked with several organizations that previously used Brevo or Sendinblue. The most common reasons for switching:

Attachment need: “We realized we couldn’t send our weekly PDF schedule — our members were used to receiving it as an attachment”
Filter issues: “We got complaints from members saying our emails weren’t displaying properly or links weren’t working — we eventually traced it to their filters”
Calendar mistakes: “An automated follow-up sequence sent an email on Yom Kippur. We needed a platform that understood our calendar.”
Support: “General platforms’ support teams don’t understand the Orthodox community’s specific needs. KosherEmail’s team does.”

The Bottom Line on Brevo for Frum Organizations

Brevo is a capable, cost-effective platform for general use. If your organization has a primarily secular or non-filtered audience, primarily communicates in English, and doesn’t need file attachment capability, Brevo is a reasonable choice — particularly at lower price points.

If you’re serving a Charedi or traditionally observant community, and especially if your members use internet filters, need to receive Hebrew documents as attachments, or if your organization needs Shabbos/Yom Tov-safe scheduling, Brevo’s standard platform will require significant workarounds or will simply leave meaningful gaps in your communication.

KosherEmail was built specifically to close those gaps — filter-compatible delivery, direct attachment support, Jewish calendar-aware scheduling, and Hebrew/RTL native support. Contact us to learn more or request a demo.
