How to Choose Maritime Email Software and RFQ Inbox Tools (2026)

The short answer: first decide whether you need to move email between ships and shore, or process the RFQs and orders that arrive in a shore inbox. They are different tools. Choose a vessel email tool on cost control over satellite, reliability on a dropping link, and security. Choose an RFQ inbox tool on reading accuracy, catalogue matching, and ERP integration. Test the shortlist on your own traffic before you sign.

"Maritime email" covers two jobs that often get confused. One gets messages on and off a vessel over expensive, intermittent satellite links. The other turns the flood of requests for quotation that land in a purchasing or sales inbox into structured quotes and orders. Many shipping companies need both. Many ship chandlers only need the second.

Two kinds of tool

Vessel email vs RFQ inbox automation

Each solves a different problem. Compare them before you compare vendors.

Question	Vessel email tool	RFQ inbox tool
Main job	Move email between ship and shore	Turn inbound RFQs into quotes and orders
Who uses it	Crew, masters and fleet IT	Purchasers, sales and quoting teams on shore
Runs where	On board and on the shore mail server	Connected to a shore inbox such as Outlook or Gmail
What matters most	Compression, airtime cost, resume on dropped links, security	Reading accuracy, catalogue matching, pricing rules, ERP integration
Typical output	Delivered email	A priced quote, a purchase order, a clean record

What to look for

How to choose a vessel email tool

Vessel email is about getting messages through a slow, costly and unreliable link.

Compression and cost control. Check how the tool compresses mail and limits attachment size, because every megabyte over satellite costs money.
Works across your links. Confirm it runs over the connectivity you use, such as VSAT, L-band or low-earth-orbit services, and can route traffic by cost.
Resume on dropped connections. Transfers should pick up where they stopped, not restart from zero.
Security and spam filtering. Filtering should happen on shore, before junk uses airtime.
Fleet administration. Look for central control of crew accounts, quotas and rules across every vessel.
Shore mail compatibility. It should sync with your existing mail server rather than replace it.

What to look for

How to choose an RFQ inbox tool

RFQ inbox automation is about turning unstructured email into accurate, priced quotes.

Reads any RFQ format. Test it on real RFQs: PDFs, spreadsheets, email bodies and scanned attachments.
Matches your own catalogue. Free-text line items should map to your catalogue item codes automatically, with low-confidence lines flagged for review.
Applies your pricing and margin rules. Every line should be costed and checked against your margin floor before the quote goes out.
Handles large RFQs. Deep-sea RFQs can run to hundreds of lines. Ask for proof on a request of that size.
Connects to your ERP. Quotes and orders should flow into your ERP or inventory system without re-keying.
Time to value. Ask how long it takes to go live and what you need to provide.

Integration

How do maritime email tools integrate with existing systems?

Maritime email tools connect to existing systems through the mail server on one side and your business systems on the other. The details differ by tool type.

Vessel email tools sit between the ship and your shore mail server. They usually connect through standard protocols such as IMAP and SMTP, or through Microsoft 365 and Google Workspace connectors. Users keep their normal addresses, and the tool handles compression and delivery over satellite.

RFQ inbox tools connect to the purchasing or sales inbox in the same way, then hand structured data onward. Priced quotes, purchase orders and invoices move into your ERP or inventory system by API, or by CSV import and export where no direct integration exists.

For both, ask each vendor three questions. Which systems do you connect to natively? What needs a custom integration, and who builds it? Can we export all our data in a standard format if we leave?

Red flags when choosing maritime email tools

A demo on the vendor's data

Insist on a test with your own RFQs, your own vessels and your real connectivity.

Replace-everything proposals

Good tools connect to your mail server and ERP. Be wary of a tool that needs you to rip out both.

Unclear costs

Ask about per-user, per-vessel, per-message or per-RFQ fees, and what happens as volume grows.

No clean exit

If you cannot export your mail archive or quote history in a standard format, that is a long-term risk.

FAQ

Maritime email, answered

What is maritime email software?

Maritime email software moves email between ships and shore over satellite links. It compresses messages, controls attachment size and airtime cost, resumes transfers when the link drops, and syncs with the company mail server. It is different from office tools that process the RFQs and orders arriving in a shore-side inbox.

How do you choose the best maritime email vendor?

Start by deciding which problem you are solving. For vessel email, score vendors on compression and cost control over your satellite links, reliability when the connection drops, security and spam filtering, and crew and fleet administration. For shore-side RFQ handling, score tools on how accurately they read RFQs, match items to your catalogue, and integrate with your ERP. Then test the shortlist on your own traffic before you sign.

How do maritime email tools integrate with existing systems?

Vessel email tools usually integrate with the shore mail server through standard protocols such as IMAP, SMTP or Microsoft 365 and Google Workspace connectors. Shore-side RFQ tools connect to the purchasing inbox the same way, then pass structured quotes and orders to your ERP or inventory system by API or CSV. Ask every vendor which systems they connect to natively and what needs a custom integration.

Do we need both a vessel email tool and an RFQ inbox tool?

Many operators do, because they solve different problems. The vessel email tool gets messages on and off the ship affordably. The RFQ inbox tool turns the requests that arrive on shore into quotes and orders. A ship chandler that only receives RFQs by email usually needs only the second.

How does Tidal fit into maritime email?

Tidal is not a ship-to-shore email provider. It connects to your shore-side Outlook or Gmail inbox, reads incoming RFQs, matches line items to your own catalogue at over 90% first-pass accuracy, and returns a margin-protected quote in under 30 minutes. It integrates with ShipNet and Bassnet by API or CSV and goes live in about a week.
