Generate Lanes

Create IP lanes or relay lanes for testing.

Event Percentages

Add Sending Domain

Force Verify Domains

Mark existing domains as verified without DNS verification. This sets all verification flags to true.

Calculate Scores

Calculates scores from start date to today in 1-week intervals.

Generate Postmaster Reports

Writes Google Postmaster rows across an inclusive date range. All rates are fractions (0-1), not percentages. Blank fields are left unset.

Where the rows show up: /v1/analytics/google-postmaster/spam-reports, /domain-stats and /compliance-reports, plus the domain spam-ratio alerts and the Postmaster summary reads. Rates are returned as percentages there, converted from the fractions stored here and entered above.

A trend shape ramps each value between a healthy baseline and the knob you set: degrading arrives at the knob on the end date, improving starts from it. Flat writes the same value every day.

Domain stats (blank fields are stored as NULL)
Compliance

Each submit replaces the whole day's snapshot: the writer deletes every existing row for the domain and date before inserting. Real Gmail snapshots carry several requirements at once, so fill in every requirement you want present in one go -- submitting SPF and then DKIM separately leaves only DKIM. A row with a blank requirement or status is skipped.

Generate SNDS Reports

Writes Microsoft SNDS rows for an organization's outbound IPs. Blank fields are left unset; submitting with every knob blank is rejected.

Where the rows show up: /v1/analytics/microsoft-snds/reports. That read authorises by sending address and skips rows whose ip_id could not be resolved, so the IP must belong to an IP lane on this organization -- which is also what the form enforces.

Volume counters

Generate Lane Scenario

Generates a lane's traffic over a date range from a preset, together with the Postmaster rows for the domains and the SNDS rows for the lane's IP that this traffic would produce.

Postmaster rows are per domain and SNDS rows per IP, so a later run for the same domain or IP replaces those days. Events add up instead: rerunning a lane with another preset keeps the earlier bounces and suppressions, and a lane closed by bad traffic stays closed for 24 hours. Relay lanes have no IP and get no SNDS rows. Below the default volumes, a single bounce or complaint can cross a day's error or alert threshold. Lane scores aren't recalculated: run Calculate Scores afterwards.

  • Good traffic. Steady volume with occasional spikes. Bounces are only unknown recipients and temporary failures (greylisting, busy servers), and nobody complains. Gmail's spam ratio stays under the 0.1% alert threshold; SNDS is GREEN with no trap hits. Defaults: 1000 emails/day; hard bounces 0.15%, soft bounces 0.5%, complaints 0%, opens 35%, clicks 6%.
  • Normal traffic. Steady volume with occasional spikes. Average bounces, including some reputation deferrals and blocks, and a few complaints. Gmail's spam ratio crosses the 0.1% alert threshold on about one day in seven and other providers' complaints on about one day in five; SNDS is mostly GREEN with some YELLOW and RED days and no trap hits. Defaults: 1000 emails/day; hard bounces 0.5%, soft bounces 2%, complaints 0.02%, opens 20%, clicks 2.5%.
  • Warmup issues. Volume ramps up from 5% to 100% of the emails per day across the range. Receivers defer the new IP for its reputation (Gmail 4.7.0 and 4.7.28, Yahoo TSS04, Microsoft 4.7.650). SNDS is RED without trap hits; Postmaster shows temporary failures for anomalous traffic. Defaults: 100 to 2000 emails/day; hard bounces 0.3%, soft bounces 8%, complaints 0.02%, opens 18%, clicks 2%.
  • Bad traffic. Steady volume with large spikes. Reputation blocks (Spamhaus, Microsoft S3150, Gmail 5.7.1) and deferrals, heavy complaints, and the lane closes on delivery errors every day. Gmail's spam ratio is above 0.3% every day; SNDS is RED or YELLOW with trap hits. Defaults: 1500 emails/day; hard bounces 4%, soft bounces 7%, complaints 0.5%, opens 6%, clicks 0.6%.
