Checking Your Guest List Before Invitations Go Out

At least 6 weeks before your intended mail date. This gives you time to chase missing addresses (2 to 3 weeks), make corrections, and submit to your stationer with time for their production window (typically 2 to 4 weeks).

You have two options: contact the guest to get their address and print a single replacement envelope, or for difficult-to-reach guests, send their invitation digitally instead. Both add time and cost.

Yes. Many couples send invitations in two batches: first to guests whose data is complete, then a second batch once remaining addresses are collected. Just make sure both batches have the same reply-by date.

Share the corrected CSV after grading, not the grader report itself. The stationer needs your data file, not the quality analysis. Fix any issues the grader finds, then submit the clean CSV.

Not technically, but your address fill rate must be 100 percent for the households you are mailing in that batch. Column structure and data quality issues should also be resolved before submitting to avoid stationer questions.

Yes. Your CSV is analyzed entirely in your browser using JavaScript. No data is uploaded to any server, ever. You can verify this by disconnecting from the internet before uploading.

Currently we support .csv files. If your data is in Excel (.xlsx), Google Sheets, or Numbers, export it as a CSV first.

Your grade is a weighted score based on column coverage (30%), data completeness (50%), and data quality (20%). An A means your list is wedding ready. A C or below means there are gaps that could cause problems. The grader checks for 22 standard wedding planning columns, including RSVP status, meal choice, table assignments, invitation tracking, and address fields used by venues and caterers.

The fastest way is to import your list into iDoTogether. Each household gets a personal link you can text or email. Guests fill in their own address, RSVP, meal choice, and dietary restrictions from their phone. No spreadsheet editing required. Most couples go from a D to an A in 48 hours without touching a single cell.

It gets expensive fast. Returned mail costs $2 to $3 per piece (stamp + envelope + reprint). Duplicate names mean double invitation suites at $4+ each. Missing emails mean you can't send digital RSVPs, so you're chasing people by phone. Missing meal choices mean your caterer adds a buffer charge. Most couples don't discover these gaps until the week invitations ship.

Absolutely. Planners use the grader to audit client lists before handoff to stationers and caterers. Many recommend iDoTogether to their couples as the collection tool because it eliminates the back and forth of chasing guests for addresses and RSVPs.

Manually auditing a 150 person guest list takes 30 to 60 minutes and you'll still miss things. The grader checks 22 columns, detects duplicates via fuzzy matching, flags partial addresses, and calculates fill rates, all in about 10 seconds.

Completely free, no account required. We built this to help couples planning their wedding. If you want to take it further, iDoTogether has a free tier for up to 50 guests and a one time $99 upgrade for unlimited.
