Source: https://trysincerely.com/for/b2b-saas Another email won't surprise a software buyer. Their inbox and LinkedIn feed are full of pitches that could go to any SaaS company. A letter is worth sending when something has changed at the account. The change might be a new executive, an enterprise launch that brings a security review, or a stalled evaluation. Sincerely starts each piece from that change. It researches the account, writes the letter, prints and mails it, and sends follow-ups on your schedule. You approve every word, and nothing prints until you launch. If your buyers work inside B2B software companies, this guide is for you. If you run a SaaS company and mail a different market, start with the [campaign playbooks](https://trysincerely.com/playbooks) instead. ## A letter written for a head of security ![Typed letter from Quillgate, a security questionnaire company, to Maya Lindqvist, head of security at Pinewick, opening with: Your new enterprise plan, launched on September 22, adds the security review that smaller deals can avoid.](https://trysincerely.com/samples/for-b2b-saas.webp "A fictional sample: a typed letter from a made-up security software company to the head of security at a software company, with the researched words underlined.") What makes it work: - It opens with a dated change. Pinewick launched its enterprise plan on September 22, and that plan brings a security review. - It names the problem before the product. The answers buyers want are usually true already, but they sit in several tools. The first questionnaire tends to arrive before Pinewick fills the three security roles it posted in August. - It offers one thing: the five answers buyers ask for most, each with the evidence it needs. - It asks a small question and says how to reply. Use a typed letter for a researched executive argument or a stalled enterprise evaluation. Use a postcard for one public message, such as a meeting request around an event. Skip generic congratulations and vague claims about growth. ## Write to the person who feels the problem first Software purchases often start with a functional leader and then pull in finance, security, and operations. The most senior title is not always the right recipient. A CFO does not own sales enablement because the contract needs finance approval. | What you sell | Primary recipient | Useful second recipient | | ----------------- | ------------------------------ | ---------------------------------- | | Revenue software | CRO, VP Sales, or VP Marketing | RevOps leader | | Finance software | CFO or VP Finance | Controller or finance systems lead | | Developer tools | VP Engineering or CTO | Platform or infrastructure leader | | Security software | CISO or security leader | Security operations lead | | People software | Chief People Officer | People operations leader | Pick one recipient for a personal event, such as a new executive. Use two or three roles for a strategic account where the decision crosses teams. ## Write when the workload changes SaaS companies announce a lot, and most of it changes nothing. A useful signal changes a priority, a budget, or a workload. - A new functional executive starts. The [new-executive play](https://trysincerely.com/playbooks/new-executive) connects the role change to work the recipient now owns. - A funding round closes. The [funding-round play](https://trysincerely.com/playbooks/funding-round) connects the financing to a dated hiring or expansion plan. - The company enters a new market, launches a product, or adds an enterprise tier. - Several job openings point to one operational bottleneck. - A qualified evaluation goes quiet after real engagement. A funding announcement alone says nothing new, because the reader already knows they raised money. Say what the company now has to do that it did not have to do before. ## Make sure someone is at the address The fair worry with software buyers is that nobody is in the office. Many teams are remote or hybrid. A letter that sits in an empty headquarters becomes a generic touch that costs more and arrives later. Look for evidence that the recipient works from the listed office: their company profile, job posts, event registration, CRM notes, or an existing relationship. An executive with an assistant, or a role tied to finance and operations, is more likely to receive office mail. If you cannot find a credible business address, use another channel. Never buy a home address. Sincerely holds uncertain business addresses for review, because a verified mailbox does not prove the recipient works there. The [B2B address guide](https://trysincerely.com/guides/b2b-mailing-addresses) explains the difference. ## Let Sincerely run the mail Sincerely runs the channel from the account list to the follow-up. You approve every piece and take the calls. - Your list stays short and qualified. Sincerely builds the audience from Salesforce, HubSpot, or a CSV, or finds software companies from a plain-language description. It qualifies each account, then adds a few current contacts whose roles fit the problem. - Every letter has a reason you can check. Sincerely stores a funding round, hire, launch, job pattern, or stalled evaluation with the account as a dated, sourced signal. The draft can make a different argument to each role. - A person checks everything before it mails. Before approval, the reviewer sees the signal, recipient, address, and final copy. Sincerely checks the budget again before dispatch. - Each buyer hears from you at a sensible pace. Suppression and frequency caps apply across campaigns and one-off sends. By default no one gets more than three pieces in 30 days, and a lower-priority piece waits for the next open day. The [frequency guide](https://trysincerely.com/guides/direct-mail-frequency-caps) shows how. - Your account owner knows when to call. When Sincerely receives a delivery confirmation, it can create a next-day task for them. It does not claim that the recipient read the piece. - The people who earned it can get a gift. For the champion who closed the deal, or a new executive worth more than a letter, Sincerely sends a gift with a personal note. The catalog has 46 items, prices start at $49, and you see the exact price before you confirm. See [gifts](https://trysincerely.com/gifts). ## See what works Sincerely records replies and meetings against each account, so you can see which letters turn into conversations. Measure meetings or qualified opportunities at the account level. Keep every contact at an account in the same group. If one person gets the letter while a colleague is held out, the colleague may hear about it anyway, and the comparison stops being clean. An executive play is often too small for a clean lift estimate in one run. Treat its replies and meetings as direct evidence, and pool only cohorts that share a qualification rule. With enough accounts, Sincerely holds out whole accounts, locks one primary outcome and window before launch, and reports lift with an interval. It labels the readout underpowered when the sample cannot support a firm answer. The [B2B direct mail guide](https://trysincerely.com/guides/b2b-direct-mail-marketing) covers the method. ## Start with the accounts already in your CRM Connect Salesforce or HubSpot, or upload a CSV, and pick the accounts where something changed this quarter. Each letter spends prepaid credits, and you see the count before anything goes out. The [formats page](https://trysincerely.com/formats) lists what each format costs.
