Tatango vs Rspamd: at a glance
What is Tatango?
Now part of momoGood, Tatango is repositioning from SMS-only vendor to a 'modern giving' platform.
Tatango was acquired into momoGood in April, and the published content since then is the rollout of a new strategic frame: 'modern giving' that spans more than text messaging. Recent posts mix nonprofit and political SMS thought leadership with explicit narrative moves — that platforms, not channels, separate winning campaigns now. The cadence is steady but consists almost entirely of editorial content, not feature releases.
What is Rspamd?
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.

Tatango
5.0COMMS
Now part of momoGood, Tatango is repositioning from SMS-only vendor to a 'modern giving' platform.
◆ Current state
Tatango was acquired into momoGood in April, and the published content since then is the rollout of a new strategic frame: 'modern giving' that spans more than text messaging. Recent posts mix nonprofit and political SMS thought leadership with explicit narrative moves — that platforms, not channels, separate winning campaigns now. The cadence is steady but consists almost entirely of editorial content, not feature releases.
◆ Where it's heading
The arc is unambiguous: away from positioning as an SMS specialist, toward positioning as one piece of an integrated giving stack. Expect product development to follow the brand work — donation pages, multi-channel orchestration, and AI-assisted message generation are all telegraphed by the recent posts. The political-vs-nonprofit dual messaging suggests momoGood will continue serving both verticals rather than picking one.
◆ Prediction
The next concrete moves are most likely AI message-drafting features built into the platform and tighter integration with non-SMS giving surfaces (donation pages, peer-to-peer, recurring giving) under the momoGood umbrella. A consolidated 'momoGood' product launch superseding the Tatango brand within two to three quarters would be the cleanest expression of the current trajectory.
Rspamd
5.0COMMS
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
◆ Current state
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
◆ Where it's heading
Since 4.1, every release has hardened parsers and closed memory-safety and trust gaps; 4.3 applies the same pass to the authentication standards themselves (SPF, DKIM, DMARC, ARC) and to content extraction. Operators should expect scores and fuzzy hashes to shift after upgrading, because the project now favours spec-correct results over backward-compatible ones.
◆ Prediction
A 4.3.x point release fixing regressions from these behaviour changes is the likely next step, as 4.2.1 followed 4.2.0 within two weeks.
