What is Krisp?
Krisp 2.83.4 brings Voice Translation into conference calls and lightens Accent Conversion.
Krisp is a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection, fraud detection and conditional recording. Call Center AI became free to try in September. Release 2.83.4 on October 26 adds a Conference mode beta for Voice Translation and makes Accent Conversion sound more natural at lower CPU cost, though the source note is truncated.
What is SMTP2GO?
Deliverability blogging with one real API release buried in the run
Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.

Krisp 2.83.4 brings Voice Translation into conference calls and lightens Accent Conversion.
◆ Current state
Krisp is a Call Center AI platform for BPOs and enterprise contact centers, bundling Accent Conversion, Voice Translation, QA scoring, deepfake risk detection, fraud detection and conditional recording. Call Center AI became free to try in September. Release 2.83.4 on October 26 adds a Conference mode beta for Voice Translation and makes Accent Conversion sound more natural at lower CPU cost, though the source note is truncated.
◆ Where it's heading
Two tracks are running side by side: security features (deepfake risk, in-call fraud detection) and the core voice tools getting wider coverage and lower cost to run. Conference mode takes Voice Translation beyond one-to-one agent calls into multi-party calls. Krisp is widening where its voice layer can run, not only what it detects.
◆ Prediction
Expect Conference mode and Fraud Detection to leave beta in an upcoming desktop release. The truncated note leaves the rest of 2.83.4 unclear.
SMTP2GO

Deliverability blogging with one real API release buried in the run
◆ Current state
Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.
◆ Where it's heading
SMTP2GO's product signal arrives roughly once a quarter and always concerns the sending path — scheduling, throughput, batch efficiency — aimed at high-volume senders rather than at the dashboard. Everything between those releases is search-oriented content built around deliverability anxiety, plus independent ranking results used as proof.
◆ Prediction
On the pattern of the June release, further API work on sending at scale is the most likely next product entry; the intervening posts will stay educational.
