Simply Noted triggers from your CRM. Pick based on who controls segmentation and measurement. Source: https://trysincerely.com/compare/lettrlabs-vs-simply-noted **Shortlist LettrLabs** if your team needs to add audience discovery, multi-touch timing, or holdout-based attribution to a program that currently lacks those capabilities. Premium includes native integrations and multi-touch campaigns; Enterprise lists holdout testing. **Shortlist Simply Noted** if your CRM already owns segmentation, cadence logic, and follow-up workflows, and you need robot-written mail inserted cleanly into that existing stack. It fits buyers who can commit to monthly volume that justifies either prepaid credits or an Unlimited plan. The core decision is whether you are buying production capacity to feed an automation stack you already own, or whether you need the platform to own targeting, sequencing, and measurement as well. ## Production and formats Both vendors use robots holding pens to write mail, but their catalogs differ. [LettrLabs](https://www.lettrlabs.com/) offers printed postcards in multiple sizes, folded formats, robot-written cards and postcards, and printed letters in handwritten envelopes. It also provides radius targeting, new-mover campaigns, Lead Reveal visitor retargeting, and weather-triggered mail as native tools [LettrLabs pricing](https://www.lettrlabs.com/products/pricing). [Simply Noted](https://simplynoted.com/) robots hold ballpoint pens for folded notes and handwritten postcards, with support for custom artwork and envelopes. Postal tracking and unique QR codes are advertised, with native Shopify, Zapier, and API/CSV workflows available [Simply Noted](https://simplynoted.com/). Both support pen-written outreach to named accounts. LettrLabs also offers several printed formats; compare samples in the format you plan to send. ## Who owns the automation This dimension separates the two most clearly. LettrLabs Premium includes native integrations, webhooks, attribution, multi-touch campaigns, and MailGPT. Enterprise adds randomized holdout testing with incremental ROAS reporting [LettrLabs pricing](https://www.lettrlabs.com/products/pricing). The platform is designed for teams that want to consolidate audience building, timing, and measurement inside one tool [LettrLabs API support](https://support.lettrlabs.com/en/articles/15904248-setup-guide-open-api-webhooks). Simply Noted supports external triggers. It accepts CRM, API, Zapier, webhook, and CSV inputs with merge fields for purchase, birthday, company, and sales-stage data [Simply Noted automation](https://simplynoted.com/direct-mail-automation). Delivery and scan events feed back for digital follow-ups. Ask Simply Noted which audience, suppression and experiment controls it provides, and which would remain in your existing stack. ## Where each is the better choice **LettrLabs is better when** your existing stack lacks campaign ownership and the relevant paid tier consolidates that work. If you need to discover new-mover or website-visitor audiences, sequence multiple mailings, or run randomized holdouts to measure incrementality, check the required tier: Premium lists multi-touch campaigns; Enterprise lists holdout testing. The [help documentation](https://support.lettrlabs.com/en/articles/15925811-what-does-iroas-mean-and-when-can-i-trust-the-number) explicitly warns that iROAS should not be trusted without a configured holdout, and that thin holdouts produce unstable estimates. Verify the holdout is configured for the campaign you are measuring. **Simply Noted is better when** an established CRM workflow already owns segmentation and timing, and you need robot-written mail triggered from its events through the integration path your team already uses. If your actual monthly volume supports the economics of prepaid credits or the Unlimited plan without leaving subscription capacity unused, it can be the lower-complexity insertion point. Teams with existing orchestration around Salesforce, HubSpot, or Shopify may prefer this pattern. ## Pricing commitments and postage conditions | Dimension | LettrLabs | Simply Noted | | ------------------------------- | --------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | | Entry cost | Starter: free platform, pay per piece | Prepaid credits or Unlimited plan | | Monthly platform fee | Premium: $399/month (confirm billing terms) [LettrLabs pricing](https://www.lettrlabs.com/products/pricing) | Unlimited: $497/month [Simply Noted](https://simplynoted.com/) | | Production per piece (examples) | Starter: printed 4x6 $0.76, handwritten postcard $1.66, card/envelope $2.86; Premium rates depend on commitment terms | Unlimited: $0.89 note card, $0.69 postcard; Prepaid: $2.76 (100 credits) to $0.84 (50,000 credits) for folded cards [Simply Noted](https://simplynoted.com/) | | Postage | Included in LettrLabs piece pricing | Billed separately at cost for Simply Noted Unlimited; plus postage for prepaid credits [Simply Noted API](https://direct-mail-integration.simplynoted.com/) | | Holdout testing | Listed under custom Enterprise pricing | Confirm availability and required external setup with the vendor | Postage inclusion versus separate billing is a material difference in total cost modeling. LettrLabs' $1.66 handwritten postcard includes postage; Simply Noted's $0.69 Unlimited postcard rate excludes both postage and the monthly fee. Compare same-size, same-treatment pieces before drawing conclusions. ## Engineering handoff and what is unknown Both vendors offer API and webhook access. LettrLabs provides a test mode that logs requests without mailing or attributing revenue [LettrLabs API support](https://support.lettrlabs.com/en/articles/15904248-setup-guide-open-api-webhooks). Simply Noted advertises API, webhooks, Zapier, tracking, and QR analytics [Simply Noted API](https://direct-mail-integration.simplynoted.com/). What remains unclear without direct inquiry: - LettrLabs: which Premium integrations are native versus require custom engineering, and whether holdout configuration demands additional services. - Simply Noted: the exact event payload structure, failure handling for undeliverable addresses, and whether delivery/scan exports include recipient identifiers that join cleanly to your outcome data. ## One practical way to evaluate Request matched all-in quotes using your last several months' volume, including both a quiet month and a peak month. Demo one complete trigger path: ingestion, suppression or failure handling, and outcome export. Price any integration work your team still owns, such as holdout randomization or downstream attribution joins, rather than assuming platform coverage.
